I am connecting a register that I bought in spring 2025 but never used.
I am trying to start it up but whether I try to login with username & password or with a device code I get a popup that says "To access your account, please upgrade your device. You can do this via your settings."
But when I go to settings (on my computer) it won't let me add that register.
Help! Thank you!
