SERIOUSLY!?

I love Pokémon Go! Its a great game and addictive. But ever since I got my new iPhone 6, I cant play anymore! No matter where I go I get a message saying, "No GPS signal found". EVEN WHEN IM CONNECTED TO WIFI! Its extremely upsetting and I would really appreciate it if this could be fixed. Thx☹️
