When hunting Pokémon with the Fam, my radar always seems to be the last to have the same Pokémon show up (usually to the rear of the radar ring). Sometimes they never show up in my game at all. It should have nothing to do with internet strength or ISP because I'm providing the hotspot and we all have the same cell phone service. Is there a trick to strengthen the radar ring signal? I've also deleted and reloaded the Pokémon Go App 3 times.
