Description of Issue

Roon 1.8 was running great
Upgraded to Roon 2.0 - have been using both remote and ARC
RAM usage has gone from low single digits to using all available RAM on the NAS
When loading Roon remote on mac, the home page constantly refreshes and kicks you out of any menu etc.

Really feels like a memory leak - screenshot shows usage of the NAS’ memory before and after installing 2.0…
