Trainers, Niantic and Pokemon Go doubled the distance from which one can interact with Gyms.
Here is everything you should know, thanks to Pokemon Go Blog:
“The distance from which you can interact with Gyms has been temporarily doubled, allowing you to be farther from Gyms and other Trainers as you challenge Raid Bosses. This change also allows you to spin Photo Discs at Gyms if you are within the doubled distance; however, it will not change the distance required to spin Photo Discs at PokéStops.”
Now, this is very helpful for those who live within this new radius for a Gym. However, those who live in rural areas don’t have any benefit from it.
Niantic said they’re still developing this new system, so hopefully everything will be settled soon.
