My TestFlight: Beta not found. A problem occurred with the public address url. Contact the developer
I have Mlem installed for almost 1 month and it works, I have also received some updates. Today clicking on the TestFlight link I got this response is the app is not there.
Ok solved, probably a new beta was released and the old one was removed from Testflight. I installed from the discussion link and the app was found and installed the new version. I think I can delete the old one
