Don't expect your bank app and other common non-FOSS apps to ever work on Anbox. The problem is that more and more Android apps are requiring the device to pass SafetyNet. Not only will Anbox not pass SafetyNet, but even de-Googled Android ROMs like LineageOS have generally lost this war.
Generally supporters of FOSS phones who have to run an Android bank app or their country’s official ID app which is SafetyNet and Play Services-dependent, are encouraged to simply get a cheap Android phone for those limited purposes. Not to expect the PinePhone or Librem to run such apps.
My bank app works on my degoogled android, and I live in the US so I think I am far from needing an ID software. I don't even have a "real" physical state ID yet haha.
