Apple Music will not log me into my Rivian

I have paid for the one year membership on my Rivian (Connect+) and now my Apple Music will not allow me to login. I sign in, it prompts me with a QR code, asks me if I want to use my Apple ID, I say yes, it gives me a code to input, I do this and the process keeps repeating itself. Rivian believes this is an Apple issue and not a Rivian issue. HELP
