I just posted a thread about this too. After you tried to edit the artist can you still view the artist screen? After I tried to edit a newly created artist, now when I now try and view the artist all I get is an Artist loading… messages.
I have create a new artist (since it didn’t exist) using the Choose Artist dialog and clicking on the “+ Create Artist”
The artist has been created, linked to a number of albums and is available in the Artist browser.
Initially the artist screen was viewable. I wanted to add a cover image so I clicked on Edit from the Artist screen and the Edit dialog was shown but it just shows the loading screen.
Now, when I try to view the artist all I get in the loading artist… screen!
