Music Library Error 301 on Apple Music Android app

Hi, I've experienced a new issue this afternoon where upon signing into the Android app the Library will not sync and I am unable to access my music.

When an Error code is provided it's mainly 301, saying there is an error loading the library and advising to check the internet connection and try again.

I have tried changing my internet connection, reinstalling the app, signing in/out, restarting my phone, downloading a system update, clearing caches, and toggling on/off the auto diagnostics send.

From what I saw online, this has been an issue for some time with little-to-no Apple resolutions provided, has anyone got any ideas?

(I couldn't locate a relevant forumn so have created this, please let me know if I've missed one!)
