I don't understand this, I use GrapheneOS and every app I've used before switching to it works just fine, including all of my financial/banking apps, Discord, etc. The only apps that don't work (for policy reasons, not due to issues with GrapheneOS) are NFC payment apps. I use both F-Droid and Google Play extensively.
