We are having an issue with the OneControl app on our iPhones. Rig is a 2017 Momentum 395M. Was working just fine on our last trip a few weeks ago. I am able to connect to the RV WiFi network with no problems. Upon opening the app, all devices show to be offline. Everything is working from the control panel hardwired into the RV. I rebooted the system in the RV with no change on the app. It is happening on both mine and my wife's phones. I uninstalled and reinstalled the app on my phone and went through the setup again. I am able to connect to the WiFi during setup, but now I have just a blank screen where the devices would be. Any ideas?
