DeGoogle Yourself

you can try looking it up on plexus to see if others have had success using that app

Has not worked for me in ages on Graphene. Same issue. It quits right away. Even tried messing with the hardened malloc and it was no go. Been a pain trying to use Zelle or deposit checks. Other than a handful of core apps I just use the web mostly at this point.

This doesn't address the app itself, have you tried using a browser like Native Alpha which can make a web page function like an app?

I know it's not the same as an app, but I find it often works well enough for me. Plus you get the benefit of not having any of the app's nonsense, like all the broadcast receivers they'll register for (screen on, so the damn thing runs all the time), or how such apps like to track things.
