Buttons seem very unresponsive in Draft

This already happened to me 3 times since the patch came out. I wanted to ban Kindred but no matter how much I pressed on the icon it didn't hover over them. It worked with a few other champion though. "I'll ban Ekko", I thought, but the ban button also didn't respond after I tried pressing it over 10 times and I ended up dodging the game (luckily it wasn't ranked).

I've also seen other players struggle to click on champions this patch and only today I've experienced 5 or 6 dodges.

EDIT: On the subject 90% of matches seem to be cancelled and you're sent back to the client.
