You can still exit a single play round through the game (you do not need to force an exit)
Yes the end game option is not there BUT now there is a “Withdraw” button. The only issue I could see is that it seems that the location of the newer withdraw button is very low (almost like it was 1/2 off the screen of my phone) so maybe you could not see it depending on what version of game you are playing. It probably needs to be moved up to the same location as the end game button
