My PMS has been empty for several days, the home page no longer displays anything even though I haven’t made any changes. I did try to roll back to a previous version of PMS (from 1.41.8.9834-071366d65 to 1.41.3-34918) but I don’t know if I did it correctly.
Did you by chance change your password and opted to sign-out all devices?
That’ll include the server itself and you’ll need to re-claim it to be able to access it from apple linked to your account.
I had the same result, an empty home page. I uninstalled, restarted the computer, reinstalled the latest version of PMS, and it works. Yet I did it several times… I don’t understand how this is possible, but at least it works
