Testing the beta of memmy, using iOS on my iPhone, and unable to log into lemmy.world. The app reports an error: ‘email_not_verified’.

Could there be an issue with the database and my account? The app’s dev assures me that he is able to log into lemmy.world with the app, so the server is not blocking memmy. Is there an issue with my email not having been verified? But then, how was I able to create my account on lemmy.world without verifying my email?
