I have just installed MC 22 on my PC and the JRiver remote no longer works..
When I tried to connect to server it asks for the access key and then just takes me to the connection summary page. It says it found two addresses, received a response.
I deleted the app on my iPhone and then reinstalled it but still get the same problem. I even restarted my phone....
I can connect to MC on my Mac and that can be controlled from my iPhone.
