The localisation service doesn't work anymore on my Ipad and on my wife's Ipad. It used to work on both, don't know what changed! Plans can´t locate me, Find my friends can't locate me etc... Whoa....I noticed that stepping out of the house the service would start to work again. Coming back into the house the localisation service stop working immidiately, "impossible to locate"!! Bluetooth is enable, wifi is enable. My wifi network is working correctly....I even did a router reset to make sure the problem was not caused by the router. Help!! Any idea why this is happening and how to correct it???
