I genuinely hate this app.
Twice in the last six months, I have been sent a message saying that “something” went wrong with my account and that I needed to reset my username. I have a pin and a recovery key stored, but was never prompted to use them. Having no other option, I followed the steps and once back in the app, I am removed from all of my group chats. I have no linked accounts on other devices. I only use it on a modern iPhone. Why does this keep happening? What an absolute grade F user experience.
