I think I have this same exact issue. The Movie Agent just simply can’t find a match, but I don’t see an error in the console, the signal is seemingly successful (see below)
I’ve tried all the suggested fixes in this thread; latest stable version, latest beta version, old agent, new agent, DBRepair tool, “Plex dance”, whitelisting IPs etc.
