Hi @Michael_Putz,
No mixup here, I was inquiring about your previous setup where you had tagged all ~40K tracks as Unevaluated until you would listen to the track.
We’re continuing to investigate a handful of potential issues linked to a degradation in performance, as there’s likely a combination of potential causes for the sluggish performance you’ve reported, all related to the breakdown of library structure. One of them being a high number of tags applied to tracks.
Another follow-up question for you:
Do you have at least one artist in your library with over 1000 tracks?
Do you have at least one artist in your library with over 1000 albums?
