I wonder if the devs have restricted its use on devices with an unlocked bootloader, or a non-factory ROM?
Discussion
I'm not sure if it's on the cashapp side or Graphene. Fold and strike work just fine. Cashapp and NFC is the only thing I have found that won't work
I bet it's reading the bootloader status flag, or the factory/non-factory ROM flag and preventing operation is one or both of them are tripped. I sorta understand their desire to prevent their system from being accessed by a non-standard device. I know they're not the only one who takes similar precautions. Some other banking and financial apps also restrict use to official, standard devices.
They’re a regulated finance company so this of probably something their compliance department requires. They also disabled Lightning features for NY users based KYC location.
I've used cashapp on a graphene phone.
Do you have play services and the store running?
