FWIW... Build 790 of 1.8 just broke Tidal connection for me (and froze Roon interface). Random picks within Tidal cause Roon software to stop working. My Roon core is on a NAS, restarting the Core App on the NAS resets Roon to work again for my own library. Random picks within Tidal replicate the above issue. Roon has had a series of quick "Hot Fixes" to correct 1.8 issues. I'm not sure they are being adequately tested and the "fixes" are becoming the problem. So, I'll be more cautious of updates in the future.
