All the time. It came up more when I was attempting to clear out duplicates from Qobuz. I deleted them via Roon. Then 10 minutes later it would sync it all back in for lots of titles. I kept doing this and then realised it was because of groupings and more importantly groups with versions that where redundant as been removed replaced. As a result it wasn’t syncing the deletions back to Qobuz so on a Qobuz sync it added them back. I gave up as have had so many issues with stuff like this an Qobuz albums. That I’ll just keep my own stuff and use Qobuz for discovery and play that I don’t own but not use favourites. Given how slow other apps are that use the api when you have a a large collection as you found in the Naim app, Bluesound was the same by the way slowed Qobuz down massively. Removed them all and it’s far better. Don’t have Bluesound now but it’s improved UAPP on my DAP hugely with Qobuz.
Anyway we have diverted the thread enough.
