When running Dex YouTube stays in mirror mode like I'm using the phone. It only goes into Dex Mode after wiping the cache and data. This happened after updating to OneUI 7 on GalaxyS 23U.
It's not just YouTube, lots of apps have this problem. See my previous post about Dex. Hopefully they'll figure out what's wrong before release, because in its current state it's almost unusable .
