Pokemon GO overworld empty, players are left with no PokeStops or Pokemon

The world is full of nothingness, but it appears that Pokemon GO is full of that too.
Several players have reported that their overworld seems to not be working properly and that there aren’t any Pokemon spawns, PokeStops, or Gyms. If that isn’t available in the game, well, what is the point then? Niantic shouldn’t even think about leaving a problem like this unsolved.
Players also said that this problem isn’t due to a device, because some Android users logged in to Pokemon GO from Apple devices, and the issue didn’t go away. An empty map is something that I wouldn’t like to experience in Pokemon GO.
All of them tried restarting or reinstalling the game, but that didn’t work. Because of this bug/glitch, many players missed the Raid Hour featuring Virizion. Niantic should do something about this as soon as possible.
