hottea I updated mine, I push update and I restarted it and hit the update again and it installed. Hope that helps.
Also I turnt that switch on in the meta app in the device settings, that switch to get the update.
Only thing I noticed was I able to play Spotify continuously when playing deo, youtube or games.
Pass through looks the same to me from previous pt update.
Other then that idk what else to look for. 🤷♂️
Oh I didn't see the home button on my tracking wrists hands, idk...maybe it's in the experimental section.
