It is a pretty smooth process but my partner got stuck in a failure mode due to removing friction like confirming email before you can start engaging with the app. A typo in the email and a password manager failing to save the generated password. This problem wasn’t noticed for days while chatting in various communities, when it was, even though their phone was still authenticated, no option but to abandon the account was available.

I’m sure it is a pretty small percentage of users this impacts but I think confirming an email address as real before allowing access avoids this wasted sunk cost and probably more importantly to small communities, avoiding troll accounts/harassment.
