Uninstall it and reinstall the latest image - Then log back into Apple music when it prompts you, and It'll work then. Something amiss in the update process, at least in my case. Good luck!
And Cider folks; Thank you - This is an absolutely wonderful app well worth the costs. Takes away many of the official apps' pain points, and adds some nice features. The DSP effects are impressive, too!.
I look forward to your future updates.
