I can’t start any of the games either with my AppleTV remote or my Nimbus+ controller which is not one of the two Plex-approved controllers. I wrote to SteelSeries who make Nimbus and here’s what they said: “The Nimbus+ uses the MFI controller standard from Apple, which is slightly different than a standard Bluetooth/USB controller. You may need to check with the app developers (Plex) to see if there’s any specific steps that need to be done to get the controller working with their app.” This controller works fine with Apple Arcade on AppleTV, BTW. Or do I need to buy a pair of Sony DualShock 4s? Like AliveKiller I can’t start any Plex Games. Thanks! Snazz.
