At work, we use several Apple TVs for presenting in meetings. Yesterday we had several meetings using several AppleTVs, all fine. This morning, I have arrived and 0 boxes are responding to the remotes. I can use the Remote app on 2 boxes as they are connected to the wifi (I try not to connect the boxers to our wifi as our wifi at work can cause the videos to skip when presenting).
Why would all 5 Apple TV remotes stop working / responding overnight (1st November) ?
