Longtime FT lurker finally creating an account due to this Delta issue.

woodenshoe101 I am encountering the exact same issue today. Opened the app on iPhone and was logged out then stated can't login with those credentials when trying to login. Tried on desktop in Chrome to the same effect. Tried resetting password via website and received MFA push to FlyDelta app (even though it's supposedly logged out?!) which I can approve successfully. Then enter a new password and submit which ends up failing.

Ultimately I assumed my account was somehow locked overnight (I was able to access it yesterday just fine). Also filled out the identity verification webform but have no clue how long it will take to receive a response or see any action.

I did not bother to try calling or deal with the website chat feature. Maybe I will need to.
