Hello @Asm0 ,
Welcome to the community,
Has the app worked before?
If it has, could you try clearing the cash, also uninstall the app, reboot the device and reinstall it?
Are you able to log-in via the website?
I would otherwise ring customer service and ask them to refresh your account and try logging in again, it should work, as it does for most customers.
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 7953 966 or +44 330 123 1105.
