I have searched all over, but can’t figure this out. My HomeKit is set up and working perfectly on my iPhone X. I go on LTE, works great. Awesome. I want it working the same for my girlfriend, but whenever she is on LTE, it disconnects from my Apple TV hub and can’t work remotely. All settings for remote are set up, I have tried logging in and out of iCloud, shutting off and on the Apple TV, making my iPad a hub, making my other Apple TV a hub, and probably some other things too. I have a Hue hub/lights set up, along with an August smart lock. Has anyone had this issue or have any suggestions for a fix? Everything is running on the current 11.3 beta. Could the final release fix the problem? Any insight is appreciated.
