Ready button not working

So im on the new client, i get in a normal draft game with one other friend. after waiting 2 minutes we finally find a match and I click the Ready button, game screen shows that i clicked the Ready button, then after waiting an unusual amount of extra time the game kicks me and my friend back to the lobby saying I did not click the Ready button. I tried 3 times to get a game but every time this bug kept happening, so I literally can not play on the new client at all because of this game breaking bug. I got a warning also for "declining" to many matches, but RIOT its your game that is broken, you cant give out warning when ITS YOUR CLIENT THAT IS BROKEN!!! Again Literally can not use the new client because of this bug. This bug has arisen just recent in patch 7.3 because i was using the new client with no major issues like this all the way up to this most recent patch. Back to the Legacy Client for a while now i guess.
