My bank app works without issue inside a private space with sandboxed Play services on my main user profile.

I also have an investment app which runs without any issue whatsoever.

Maybe I’m lucky and these Canadian companies just aren’t dicks about mandating google.

As far as I’m aware, as of now, graphene does not meet googles attestation (Uncertified Device), because google says so, but is easily more secure.

Google’s lockdown has zero to do with security.
