Need help getting started with memmy

Using on iPhone with iOS 15.7.6 with TestFlight. Prompted to create an account or log in to existing account. Chose the latter. Keyed in my server (https://lemmy.world), next keyed in my u/n, and then my password. Reported error: 'email_not_verified'. Unable to log in.

UPDATE: Thanks to @gkd@lemmy.ml (memmy dev) and @ruud (lemmy.world admin), now able to sign in. Ruud reported that curiously my email had not been verified when I signed up and created an account on lemmy.world.
