Thanks for explaining the issue,
Can you please advise what device you're using the app on, and whether you've tried downloading the app on a different one?
I'm using a Vodafone X9 android phone and I've tried it on my wife's Huawei Android phone.
It's coming up with the same page as posted above.
I've run through a few checks and looks like I'll need to raise an IT ticket for this one.
I've popped you over a private message so I can get a few more details from you 🙂
