Gym errors are very annoying and after all this time, Niantic has not solved it yet. It seems to be more of a server issue most of the time or can also see a gps issue due to poor service in a certain area. You can read more about Gym errors here. But lately, I’ve been doing a technique in order to avoid these errors. It saves us time as Gym errors often makes it harder for us to train gyms.
- Just go into a Gym battle, select your desired Pokemon.
- Turn off your GPS after you’ve hit go.
- Turn the GPS back on after the fight.
This technique has been proven to work on Android. You can use this for both conquering and training gyms. Try it out for yourself and have fun trainers!
