Problems adding money via App

Issue:
Unable to add money to my account via app no matter which source it is coming from. I have tried to uninstall and reinstall the app but having no luck. When I go to type in the amount to transfer, it won’t let me do this.

Details to reproduce:
OS:
Android

Device:
OPPO A94 5G

App Version:
5.0.1

Screenshots:

So when you tap the £0, you cannot type a different amount?

It might be an issue with your screen/resolution that’s not showing something you need. But I tried the same route and once I type an amount, I can progress.

Has it ever worked? Or has this recently happened?

It definitely looks like a screen resolution issue, there is text at the top that is being cut off/not displayed
