We’ve taken a look at logs and see at least some updates to your Roon library being completed from the Tidal API (as of today). Approximately how many albums have you added to your Tidal library via the Tidal app/web player that have not yet appeared in Roon?
I’m assuming you’ve already tried signing out and back in from Roon Settings → Services, but please take this step once more after rebooting your Roon Server machine.
Our diagnostic servers show recent account activity and some active syncs with the Tidal API since you last posted. We’re going to assume this issue has resolved and allow this thread to auto-close, but you can reactivate it by submitting a new request here anytime. Thank you!
