Accepted Gyms and pokéstops disappears and give error 2
Since you did the maintenance in Pokémon GO, errors have been reported in stops and gyms accepted. If you try to leave a pokemon in the new gym, the game says "error 2" and does not let you put anything.
After a few hours, the stops disappear and the gyms go back to being pokéstops, or both disappear from the game.
I hope you fix it soon, it is a very annoying error, especially for those of us who work with wayfarer to improve the gaming experience.
I attach some images from different players who reported me in case they help to see the problem. Greetings!
