Pokemon GO Verizon code troubleshooting for a treat fix

Today Verizon announced a Pokemon GO code and special event exclusive. Niantic and Verizon are the latest brand team-up to make Pokemon GO take on another shape, this time with an event, new masks, digital billboards, and a "5G demo" in the game. To participate, you'll need to be a Verizon wireless customer - or you'll need to know someone who is a Verizon wireless customer that'd be willing to give you their code!
