I've set up JRiver Media Center 33.0.72 on my new M4 Mac mini running Sequoia 15.4.1 and have JRemote 3.44 on my M4 iPad Pro running iPadOS 18.4.1.
I used the acces key and the authentication which are both set up in MC 33. JRemote works wonderfully and I can do everything except change the ratings on a song. Any change I make in JRemote does not show up in MC 33. In fact, if I change a rating while a song is playing in JRemote,it reverses to the prior rating when the song finishes and the next song starts.
I've tried changing the authentication code in MC, and I've deleted and re-added the server in JRemore. Neither made any difference.
It seems there is something flakey with the authentication. I'd appreciate any help.
