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.
Maybe not ideal but I’m sure the web version of your banking app would work through a browser.
It does, but it’s not designed for mobile. I would send a screenshot, but I don’t trust myself to censor everything important.
Try to use a desktop, try different browsers if needed, if you cannot, you may need to physically go to the bank.
