+1, same issue. Oculus Quest 2, V28 (latest).
To reproduce: Start app for first time, give storage permission, exit app, start app again. Endless loading circle. No connectivity issues.
EDIT: Fresh installed the app. First startup works, then the issue reoccurs.
PS: Only other out of ordinary info that might be relevant for me: using multiaccount feature, downloaded and started app on secondary account.
EDIT 2: The bug only occurs on secondary account. Might be linked with storage access issue but I reported.
What does work: terminatin, clearing app data through settings.apk. But that only fixes the issue for the single initial launch.
