Thanks for writing in and sorry to hear about your loss of downloaded tracks!
Updating Arc shouldn’t affect your already downloaded tracks. We were able to see recent Arc diagnostics, and see some download failures due to a severed connection to your server - how are things running now?
Are you able to re-download tracks?
Where do the local tracks typically live, and how are they imported into your Roon Server?
Thank you for taking care,
I downloaded the files again and so far it works.
My files are sitting on an ssd in the exasound server.
They are getting there from my Mac via network.
I never had an issue with the exasound server.
regards Burkhard
