Loads of people having issues with the app after a recent faulty update.

You should be able to login to MyO2 using any browser at  https://accounts.o2.co.uk/signin

If browser login works, uninstall the app from your phone, reboot and reinstall,  to see if that helps. Otherwise contact O2.

All methods of contact here Guide: How to find help & contact O2
