I have found ~3 Pokémon out in the wild I have wanted to catch but when I try to tap them on the map but it doesn't do anything. They eventually run away/disappear after a certain period of time.
When I do manage to click on them to start the battle, I can throw the Pokéball just fine. It just sometimes won't load off the map and onto where I catch them I guess.
I do have my location on and have Wifi! I need help to Catch 'Em All!
