I can’t root my phone because I don’t have an image for it (Moto G73) although I’d like to, but for some reason my banking app thinks it’s rooted and refuses to work. This happened just after I updated it, it wasn’t happening before.
Edit: I’m regretting not getting the Motorola Edge 40 Neo, which also costs £250, but is slightly better in multiple ways, and seems like it has better root support.
Try to use a desktop, try different browsers if needed, if you cannot, you may need to physically go to the bank.
