Unfortunately, this is probably because of the apps started using the Play Integrity API, which is a hardware-based attestation and can only be faked in two ways that GrapheneOS isn’t interested in:

• you can fake an older device that didn’t support hardware attestation yet, or had a broken implementation
• or you can try getting leaked vendor keys and emulate the crypto with those until they get revoked

It’s only backwards because you’re looking at it from the outside from the front. When it’s in you, the left is on your left.

You can disable the NixOS firewall, install firewalld (or any other firewall solution) and use that if you want.
