You can use cash.app in Vanadium - you must checkmark Desktop site in Vanadium for the web app to work on mobile, ironically. But it does work. You can still make payments, etc. I added a shortcut to the home screen.
I don't know when this changed, but when I got a new Pixel a few months ago and went to install my apps, I was running into all the same problems mentioned above. It worked fine on my old Pixel 5a.
