Android Auto•11/16/2023
In the time that I've been waiting for this to be resolved, I ended up switching temporarily to an iPhone to use with my wireless display, and that process worked just fine. Shortly afterwards, my display was damaged and I replaced with a different model. I tried wireless android auto with this display and to my surprise, it seems to work fine. I don't know if it was a display unit, or recent app update, but I'm happily using Wireless Android Auto once again.
