I have this issue from time to time usually due to lag on either my side or their servers. I think its because the pokemon still appear from your end but are actually despawned already.
auto update-option in fake gps?
I'm having this issue as well and It doesn't get fixed unless I reboot the Android Kernel in Nox , any other alternatives without the need of rebooting ?
I only have delay of like 3-4 minutes (when I compare it to my PC time) and when I restart the android kernel , they become the same then after few minutes , It gets delayed by 1,2,3,4?? minutes .. anyone pls ?
