Hi all – we believe there are actually 2 issues at play here.
One is some server-side instability that we believe has now been resolved, but which we are still monitoring closely.
The other issue related to a bug which would cause TIDAL syncing to never fully complete. The endless syncing was causing a number of issues, including instability and the failure to add albums to your library described above. This issue was local to the Roon Core, and is resolved in Build 94.
We’re interested to know if this issue is resolved for everyone, but this thread is extremely long, so I’m going to close it. If you’re still having any issues adding albums to your library, please start a new thread and be sure to let us know all the basic info about your setup.
Thanks everyone!
