Hi @hmack,
Looking through your Roon logs, I am seeing the following traces when trying to access TIDAL content:

And I’m even seeing Airplay lost packets when playing back content:

All these traces point back to network instability somewhere along the line, my first suggestion here would be to replace the ISP-provided router with a consumer grade one, I strongly believe that a new router would greatly help with the issues you are experiencing.
