I share an oculus quest 2 and I'm on the second account. The admin account's games save all the progress but the second account loses the game progress. For example, in beat saber, my high scores are gone but it still shows my place on the leaderboard. Also in I expect you to die, I had already completed multiple levels and it made me restart the game after a day.
In https://support.oculus.com/articles/accounts/multiple-accounts-and-app-sharing/index-multiple-accoun... It says that all accounts have their own In-game progress, high scores and in-app settings. There might be a way to make all accounts share the same progress and stuff.
