All of my previous activities are missing
If you can't see your previous activities on your Profile, you might have logged into Relive with a different email address. This often happens if you use Relive on a new phone or reinstall the app.
To fix this, you can log out of your current account (go to Profile > Settings > Scroll down > Log out) and log back in with the email address you used before.
If you don't remember which email address you used, check all your email inboxes for a welcome email from Relive. The email address that received the welcome email is the one you should use to log in to Relive.
