My FaceTime calls are lagging. The cellular data is on. This happens using the house Wi-Fi and it's connected. No other incoming calls that are interrupting the current FaceTime conversation. It happens constantly and has been getting worse.
I am now back on Wifi and this seems to be better. I do have an older iPhone SE which still works great. Our connection speed has been great as I check it often. And hopefully it gets better with the new Fiber Optics.
