I have the same with my banking app here in The Netherlands. I don't know if they try to be a super app, but since a year or two they put all kinds of annoying ads inside their app and unnecessary notifications on top of my account overview. Just show me the numbers, I pay for your service.
It's the same with mobile payment. AFAIK there isn't a single bank left in The Netherlands which has its own mobile tap-to-pay app, everyone has switched to Google Wallet.
Good for them that they want to save a few bucks on developers, but why do I have to give my payment info to the devil? It's a third party which has nothing to do with the payment itself, and the fact that some banks used to have their own tap-to-pay apps shows that it clearly isn't a technical requirement.
