I have Roon installed on an Antipodes music server the uses a Linux OS. I can control Roon with my Apple iMac that is connected by ethernet to my network.
I prefer an iPad as the controller and have been using the iPad since I first installed Roon on my music server. For the last month I am having issues with the iPad connecting to the core.
This has started since I updated my Roon Server to the latest software.
The version of Roon is: Roon Server Version: 1.2 (build 161) stable.
The iPad iOS version is: 10.0.2
