srp issue with auth

[rzdvDev]

I have an account with an account upgrade step (connecting 2FA), and I can't log in with error 412 "authType": "sa."
I looked at the requests the browser sends to complete this step, and it's sending a GET request to https://appleid.apple.com/account/security/upgrade/setuplater.
After that, login works. How can this library be used in my situation?
i use latest version of library and python 3.13.12

@rzdvDev - If you are able to give me a full trace of a working login flow and the broken one. I will be able see what can be done. Unfortunately, I am unable to replicate this as I have no accounts that require upgrade.

Happy for you to send this to me privately on Discord.
