I have 3758 albums in my library. I use a custom tag to also keep track of my albums in Collectorz.com. I use a custom tag to identify an album in my library that has also been entered into Collectorz.com. All 3758 albums (minus a few I added this week) should be tagged as in Collectorz.com. Roon reports only 1795 albums with the Collectorz tag. Almost 2000 albums have lost their tags. Now I’m wondering if any of my other tags are working properly.
