By providing an option to sign out of profile or account in the Quest Home space itself, via settings perhaps. But more so see below.
You sell the Quest title In Death: Unchained Season 3. For over a month it has been going into a frozen state with "syncing" on the game jacket in the quest homespace/library. I've had it happen four times now. On all the prior 3 chat support sessions I've been advised to factory reset the device from the app. This is obviously a troublesome option for fixing the error.
I want to put up an appropriate solution/work-around I just now worked out for other users, that is until the developers at Superbright workout how to fix the bug. It is the Cloud sync that freezes, which the game does when you close it. Apparently the connection is being lost (I suspect as being the cause), thankfully it doesn't then become a problem when you launch the game, as it does a Cloud sync then too.
To fix a frozen In Death: Unchained Season 3 you:
1/ Open Library option from Mobile app after ensuring it's registered as connected in the app.
2/ Locate the game in your library and touch it.
3/ At the bottom of the screen you'll see a blue rectangular box that has Start listed, touch it.
4/ Put on headset, you'll see an option to download latest update, select update.
5/ Once game has had the update installed there'll no longer by "syncing" present on its jacket, launch game.
