Hi @gsuzor91,
Thank you for your very helpful summary, and for sharing publicly on the forums. I’ve passed this along to the QA team.
The most recent release of Roon and ARC (released today, notes here) includes numerous adjacent stability fixes. While we haven’t precisely resolved the underpinning issue with the tag sync error you encountered, I’m curious to hear if you encounter any unpredicted issues on the new build after updating. Hopefully, all is well!
