Halifax UK. It just refuses to work so I left it (Graphene is more secure, so forcing less security for the sake of tracking is off the cards). All the other banks so far say they won't work without Google services but if I click OK they work

Not OP, but I've been on GrapheneOS for a few years and I have no problem with Chase, CiT or Wealthfront. I mostly use them to check balances and unlock debit cards, but they all login and function fine.
