Nepeo thanks for checking out the Google Play Services behaviors in my game and for the detailed reply. And glad you can appreciate the potty humor. (Apple sure didn't because they rejected the game. lol)
Interesting theory about leaderboard/achievement loading slowly due to lack of players. THat could be true with this game since there aren't many downloads.
Good idea about having the buttons do something to let the user know it has been pressed, and that we're "waiting on Google". Maybe a small pop up message/dialog box. I'll have to do some tests... but is there an event I can use to trigger when to hide the pop up/dialog?
And no, I wasn't aware you added the "welcome back" and "achievement unlocked" pop ups. That was my next request. Awesome! Going to test...
...I just rebuilt my game with the latest release and the "welcome back" pop up displayed on login. Still need to confirm if the achievement shows (It might take a while to unlock the next achievement since I've unlocked a few already).
Again, really happy that everything works and that you added the new features to the plugin. Great work!
