[2019] What is this Auto Ready Up thing and can it please be removed?!

Title says it all. this Auto Ready Up feature or bug that has been happening the last couple of days is really annoying. Sometimes I wanna take a break between matches to change skin or go to the bathroom but it just readys me up anyway and it won't let me cancel it! If this is a feature they really need to rethink it and remove it because it is really annoying!
