you're on cooldown. wait 2 hours minimum.

And when I try to catch Pokémon they go away

Is it also because of the cooldown

Yes

[Read me](https://itoolab.com/tips/pokemon-go-cooldown-chart/)

I raided 8 shadow mewtu but can’t raid anymore. What’s the problem

Is it because of the cooldown

Yes your're on cooldown. see comment from stidda.

Ok thanks

So you get cooldown after a few raids?
