today, my wife told me that copilot had really bad reception. she usually turned off wifi. I told her turn on wifi option when she will come to home today and see it will work or not. I recently had same problem then I thought maybe there might be some connection between software and wifi option in Iphone so I turned on Wifi option at Iphone setting. after I turned on Wifi option. a reception problem was gone. am I missing something? Does anyone have same experience? or Am I supposed to turn on wifi while I am using copilot?
