Banking apps are highly variable, many work, many don’t. I have also heard that there are some required 2FA apps used some some European banks that currently don’t work. I don’t use any of these, so it hasn’t been an issue, but I just wanted to make sure the OP knew to be on the lookout.
Banking apps have worked without issues, in my experience.
The only things I’ve had issues with, is in-app purchases. Paid apps work, but the in app stuff is hit and miss.
