I can remote start my lariat from in my office, in the middle of the building, thru 5 different walls with my key fob. Best fob range of any vehicle i’ve ever had….

Yeah the app is shit and I hate it, especially since they removed the Journeys (and where the hell did the acceleration analysis go??) but I find the lock/unlock feature useful when I forget the keys and I'm just grabbing an item.
Can confirm - I've seen this episode and tested it in a large parking lot. It actually works, and far better than it should.

Lariat comes with the fancy keyfob yeah? I'm curious if the antenna in that keyfob is just more robust than the typical XL/T
My XLT one seems very strong on signal. They are different though. I understand the app frustrations. I rarely use it unless I have to but my keyfobs work great. Hope it gets figured out for you. My escape is only about 30 feet range but pretty sure it's weak batteries. Not original owner so no clue how it was "fresh".

The 2X with the circle arrow headed button is for remote starting your Maverick. To do do, you have hit the Lock button, then the 2x button twice in quick succession. If it's successful you'll see a little green light on your fob, but you need to watch for because it happens quickly. If the process didn't work the light will be red.
Thanks, maybe I can remember when if ever I want to remote start. Am guessing the 2X label is code for push it twice,
. That should along with the circular arrow being code to "go nowhere" will help. Though generally I have trouble remembering associative clues. I have been known to reinvent obvious items multiple times.- Thread starter

Update 7/6: Service department wants to hold the truck for 5-7 days while they work through tickets, figures dealer wouldn't be much help for a "non-issue" like this.
Does anyone with a service manual have a diagram of factory-antenna location(s) for the keyfob transmitters? I'm hoping its a matter of the factory either not including enough or placing them in a location with interference.

Think I found it:
RTM
The RTM communicates all RKE and passive key information to the BCM over a LIN circuit and when awake the CAN . The RTM is an antenna that receives the high frequency signals from passive keys. For additional information:
Refer to: Handles, Locks, Latches and Entry Systems - System Operation and Component Description (501-14 Handles, Locks, Latches and Entry Systems, Description and Operation).
Refer to: Tire Pressure Monitoring System (TPMS) - Vehicles Without: Keyless Entry and Push Button Start - System Operation and Component Description (204-04B Tire Pressure Monitoring System (TPMS), Description and Operation).
Refer to: Tire Pressure Monitoring System (TPMS) - Vehicles With: Keyless Entry and Push Button Start - System Operation and Component Description (204-04B Tire Pressure Monitoring System (TPMS), Description and Operation).
The RTM requires PMI when replaced. For additional information,
Refer to: Module Programming (418-01 Module Configuration, General Procedures).

RKE (if equipped)
The RKE feature is controlled by the BCM . When a button is pressed, the TIC and RKE command is
received by the RTM (remote start vehicles) or the BCM (non-remote start vehicles). The RTM (remote start vehicles) interprets the information and sends a message to the BCM over a LIN circuit and, when the network is awake, over the CAN . If the BCM detects a programmed key, it carries out the command by controlling the door locks or activating the horn or turn signals as required. The BCM (non-remote start vehicles) interprets the ultra-high frequency signal from the passive key via its internal receiver. It then processes that information internally and carries out the command by controlling the door locks or activating the horn or turn signals as required
The RKE system can be used to:
l unlock the driver door and tailgate.
l unlock all doors.
l lock all doors.
l arm/disarm the perimeter alarm.
l activate/deactivate the panic alarm.
l remotely start the vehicle (if equipped).
l configure the staged lock programming (2-stage unlock or global unlock).
The RKE transmitters have a normal operating range of 30 m (98 ft) in an open air, no obstruction
environment.
The RKE transmitters and the BCM also utilize a rolling code to prevent the code from being captured by a code grabber. The system advances the counter in the RKE transmitter and the BCM every time a RKE transmitter button is pressed.
The message center displays Key Battery Low Replace Soon when the battery in the passive key (if
equipped) needs to be replaced.
RKE Transmitter Unlock (if equipped)
The RKE provides a staged process for unlocking the doors and tailgate. Upon receipt of the first request for unlocking the doors, the RKE feature unlocks only the driver door. If another unlock request is received within 3 seconds of the first, all the doors are unlocked. This feature can be disabled so that all the doors unlock on the first press of the unlock button (global unlock) through the message center.
Vehicles come from the factory set with the 2-stage unlock feature disabled (single press unlocks all
doors).
RKE Transmitter Lock (if equipped)
The RKE requests all of the doors lock and tailgate when the lock button is pressed.
The RKE feature is controlled by the BCM . When a button is pressed, the TIC and RKE command is
received by the RTM (remote start vehicles) or the BCM (non-remote start vehicles).

So the short of it is likely a new RTM is needed for my case, reprogrammed keys n tested votages already but that's also where the service manual seems to end on it. Dealer already said they'd not prioritize (duh) and even if they had the RTM is definitely, for sure, on backorder.
Take me back to the days where we didn't have no fancy remote locks and electronic keys, we locked our doors with a metal stick! And started the car with a different metal stick, both ways! and we liked it damnit
