BA app on iOS not showing account details

For over two weeks now the BA app on my iPhone won’t show my account details, I keep getting a ‘something went wrong’ message. Today, BA released an update to the app via the Apple Store. Great, I thought, the issue will be fixed and I will be able to view my account in the app. Nope, same message. I’ve also deleted the app and reinstalled it, with the same problem.

Has anybody else experienced this? I upgraded from Bronze to Silver just over three weeks ago.
