I have a game published on both Apple and Google stores which uses the GameCenter commands for maintaining a high score board on both platforms.
On Google, the score board no longer functions. The game signs in and displays the welcome message ok, but when the scoreboard is called it fails to display. This used to work, and was working last week when I shared the weeks top players on social media. Cliff Mellangard 3DEGS made a post about the email we'd received from Google about deprecation of the Google+ and associated sign in stuff, and I think that's what's causing the issue I'm having on the Google version.
On Apple, I find that I sometimes have to run the app twice in order for the sign in and welcome message to occur.
