A lot of folks here are having a sync issue that an update takes care of. Among those issues, for me, my CarPlay dongle did the same as your AA. I did a master reset and update. For the moment, It seems to have fixed the issues that have been noted.
I bought 36ā black strut channels from Grainger. 14 guage looks better than the 12 guage imo. The eye bolts canāt slide past the mounting bolt heads on the 14 guage so put in an extra eye bolt as well for full coverage.
