Hello @Turnersplot ,
Welcome to the community,
There are many threads about this, giving suggestions what to do.
Try clearing your cache, make sure that your app is up to date, try uninstalling it and reinstalling it, see if that works, otherwise the other option is to ring customer service and ask them to reset your account.
You can always log in via the website rather than use the app.
To contact EE customer service dial 150 from your mobile phone or ring customer service for free using web based app or another phone: +44 800 079 8586 or +44 800 956 6000.
