Hi @Robert_Lidstrom,
We’ve activated diagnostics and taken a closer look at the timestamp.
RoonServer is processing the album addition and importing the album. However, the next Tidal API sync with your library prompts an invalid request error code from Tidal’s own servers.
Their API’s descriptive message for the rejection indicates Tidal’s servers are rejecting the album addition request because you have exceeded your 10,000 favorite maximum.
Other users have described their experience here: Cannot Add More Tidal Albums to Library - #5 by Tommy.
Unfortunately, this limit is at Tidal’s discretion and beyond Roon’s control. They’ve been stern about Favorite Limits in the past.
