"Anyone else getting indoor GPS issues?"

#PokemonGO: A lot of the time when I play my game indoors, I get "GPS signal not found. (11)", the same error you'll see if your location is turned off. Only thing is, my GPS is already on! None of my other GPS using apps have any issue while indoors except this one. I've had this for a few months now, anyone know how to fix it? I'm using an S7 edge running android version 7.0. via /r/pokemongo https://ift.tt/2Ql07t1
