@bobby4wales , have you tried uninstalling it and reinstalling the app from the App Store or play store? If that does not resolve the problem, you may want to clear the cache or ask customer service to reset your account, as the app does work.
You can always log-in to your account via the website, as this should work also, without any problems.
To contact EE customer service dial 150 from your mobile phone or ring customer service for free using Skype or another phone: +44 800 079 8586 or +44 800 956 6000.
