There are no conseqeunces for reconnections from the game's side. The new screen is a method to help getting around the "Spinning Castle" problem, where the game is in a state that you cannot connect to it, but the game tries an infinite amount of time. This kept players from playing for hours and days sometimes, before they asked for help and got told the method to ger around it.
Now, if you try a few times and it doesn't work, you can accept that the game is in that state, and leave it by choosing the "go to lobby" button.
