I have similar issues as @Mac_Rebant, and i need to regularly restart my core to maintain search capability. I cannot click the album links on the “now playing” page, Roon stalls with the animated Roon-icon claiming it’s “Loading album…”. I have to find the album via the hamburger menu.
I agree this is the slowest and most unstable Roon version since 1.1 (when i joined)
