Lobby Delay Upon Accepting Game in New Client

Title says it all -- I don't know if anyone else has this problem or not, but I experience this problem in the new client exclusively. The legacy client works perfectly -- it isn't my connection (hardwired and able to run multiple games at a time -- such as LoL and Overwatch + Blade&Soul). In many cases, it times out completely without disconnecting me -- which causes dodging and other issues. It is nearly impossible for me to even get into a game using the new client. Is there a fix for this or is this just a result of the client still being developed? I believe this is a bug issue in the client itself. Am I wrong?
