spoiler: i dont. i dont need to, simply. my bank can be accessed fully through the website, and that is how i use it. most services i have i use through email or some other form of interaction that does not require an app. i simply do not use these services, and thus i dont need to even have an app for them. if im lucky, it will work on waydroid, but i dont have a lot inside waydroid. so, yeah, it is easy for me as of now at least.
This is also my approach. I use the bank websites. If any dirty fiat banking cartel or other group try to force their app down my throat, I simply take my money and go elsewhere!
This is the only way we can solve this. $$$ is the only language these crooks understand.
