Please refer to reply #13 on page 1 - in addition to those notified bugs I failed to notice that the leaderboards are also not sorted in order according to the ordering established in Google developer console. You'll see in the image in that post the they are listed > easy, hard, medium.
So it's both leaderboards and achievements are not being sorted in order in iOS. on Android they are in the correct order.
To recap the bugs I've found are listed below - I hope this helps you patch these bugs. And I do hope you can update me on fixing these as my game is nearing completion. Please let me know timescale as otherwise I might need to get a refund and look at one of the other options. Hopefully not as other than these issues your plugin is doing the job!
1. iOS only - the incorrectly drawn title box on Google Play panels. (and/or status bar showing) - not the highest priority problem for me although doesn't look great so if it can be fixed great.
2. Android only - no 'welcome back' on sign in after closing app from multitasking and reopening (where sign in is automatic) - edit to this one. I have noticed if the app is just closed but stays active in b/g then after a long delay and returning to game you do get a 'Welcome {name}' box.
3. Android only - the no leaderboards/achievements working on 1st (and every other) sign in. Although works with my double-sign-in work around. (thought - maybe the double sign in trick will fix (2) as well? will check. edit: checked this, it doesn't work)
4. iOS only - the achievement slide up panel has a transparent background(border) which turns black after completing slide up. This looks wrong and is not same as leaderboard slide up which has solid grey b/g as expected.
5. iOS only - unordered lists of leaderboards and achievements. i.e. not according to the sort order given in the google console. (1/5, 2/5 etc...)
