Insta troops donation bug

Hi. It’s happening 3rd time with me. First 3 days ago I donated someone just one insta and suddenly my game reconnect and I see that all my insta donation are on cooldown and the insta I donated was not actually donated. And again today I donated one insta to someone and he got max instas. When I restarted the game again all 5 donation wer on cooldown again. I’m sorry if I cant explain correct. Thanks to my poor english. IGN: Prince_Dastan android 6.0.
