A warm welcome and thanks for posting on our community forums. We do apologise that you're still experiencing issues when trying to log in to your O2 Priority App.
We do have some trouble shooting steps which may resolve the issue. Can we ask if you're currently using an Android or iOS device, also
- Which handset are you using?
- Which app version are you using?
- Which OS do you have installed (please include version)?
- Have you registered for a My Virgin Media account online and do you also have the My Virgin Media app installed? If you do, are you able to log in and view your account details (package etc) in the app?
Kind regards Jodi.
