Description of Issue

For last month or so have not been able to connect to Roon via iOS, ipad or phone.
I get the message unable to connect or find core.
If the iMac system output is running on screen it will sometimes connect, but will not if the computer has not been active for a while. I have reinstalled everything and followed the set up guide.

Having similar issue.
IPad remote can’t find core: “waiting for Roon core.”
But I can always connect from a windows pc or any other device.
If I reboot the iPad then it works . . . for a while. Next time I use it, same problem.

Same here. I posted this in iPhone thread but it is gone now. Hmmm. Anyways latest IP 14 and latest IOS and latest Roon. Every single time I just want to play a few songs I cannot. And yet they now want 30 more dollars from me? And they do not respond to any of these iPhone / IoS issues. WTH???
