Signing into my o2

[Lyndsey3]

I have tried multiple times to sign onto my o2 with no luck and I have changed the password

Seems a perennial problem.

Can you sign in Via the Website.

Could try deleting and reinstalling the app otherwise

They should be able to help you.

The suggestion by @Enlli to delete and reinstall the app is well worth a try, but after deleting, I would suggest that you restart your 'phone before reinstalling the app.
