Real unfortunate news for GrapheneOS users as Revolut has decided to ban the use of 'non-google' approved OSes. This is currently being posted about and updated by GrahpeneOS over at Bluesky for those who want to follow it more closely.
Edit: had to change the title, originally it said Uber too but I cannot find back to the source of ether that's true or not..
So, uh, the next version of GrapheneOS will probably come with some Android OS version spoofing tech that solves this - if there isn't something on F-Droid already.
