Hi @Osamu_SHIOTANI,
Qobuz is rolling out a fix for a known issue affecting their metadata for import date. This can cause what you’re seeing in Roon for Qobuz content. The fact that Tidal content shows the exact same date, however, suggests that something about these repeated database migrations between Early Access and Production reset the import date to the date of the new sync. Did you restore from a Backup when you migrated between EA and Production, or just download the EA track?
Since streaming content relies on service-provided metadata rather than a fixed local timestamp, these values can shift if Roon reprocesses the library. Unfortunately, once this happens, there isn’t a reliable way to restore the original added dates unless you have a backup from before the change.
If you do have a recent Backup from before the date added that is listed in Roon, try restoring that in the meantime.
We’ll watch for your reply.
