TFT is a great game, and I've had a good experience with the app until recently. Riot has added email 2FA (great!), but now I literally cannot log in on mobile: Open the TFT app; must sign in. No problem, open password manager app to get my password, copy to clipboard. Go back to TFT app. Oh wait, it's gone (seems to close if you switch apps). Restart TFT app, enter password. Now I must enter an email code for 2FA. But when I switch over to email app, TFT closes, and the cycle continues...
