Why am I 30 seconds behind on raid bosses?

[Squadlife]

Every time I enter a raid boss I'm at least 30 seconds behind compared to everyone else. And if they beat the boss before I get in I get an error cause the boss was beaten before entering. It's frustrating cause I lose out on raids, especially tyranitar. My app is updated. I'm using a xiaomi redmi note 3 pro and I haven't had any problems since this update other than the normal updates. Any one know?
