Not banking apps here, but a few of my apps (Target.com and State Farm's Drive Safe and Save) do the exact same thing - loading screen pops up for 1-10 seconds, and then the app just quits. I'm on a Pixel 5 with Graphene, and just installed it on a Pixel 4, and the same thing happens with both apps on the most recent 2023100300 after a reboot and app delete/reinstall.
