GPS Woes
The is a gym where I live in a Starbucks which is in a large supermarket. For some reason the gym is located in the center of the supermarket (while the Starbucks is near the front on one side). When I walk into the supermarket, my GPS seems confused and according to it I am still at the entrance. When I am right at the gym I am unable to train because my GPS indicates I am still at the entrance.
I don't see how anyone can battle this gym! Or perhaps, other phones have better GPS? I am using an iPhone 5c, which is pretty old.

I believe wifi also makes a difference so if someone were connected to the supermarkets wifi (if there is any) they should be able to get to the gym. Their also could be weak cell phone coverage that could make people with a different data roming company the upper hand. I don't think phones make a diffrence scince I'm using an iPhone 7 and having the same issues on some pokestops and gyms.
