Can't accept ready check.

When i queue up to find a game it doesn't let me accept the ready check. It just show me the accept button for like 0.5 sec after it's too late and tell me i didn't accept it. It happens pretty much half of the time and not just on the new client it, on the legacy one too. Also, in lobbys I sometime can't pick, lock in or ban because the client freezes and I can't do anything so it eventually just disbans the lobby. My connection is perfect and get 30-35 pings in game which means it doesn't come from bad connection. I'm getting 5 and 15 minutes queue block because of this and would be incredibly pissed if i get banned because of it (more than now). Please fix this presto because it prevents me from playing and has been doing so for a while. [slayer-jinx-unamused] this is me but way more pissed...

Thank you.
