Merge Academy - Won't save progress

Mine too, except after a couple of times of trying I would save and exit and quit and then I went back in just a couple of minutes later and in Treasure Trove and the main game I was back on 100 energy for both and nothing was saved.  I have just tried going back into the main game and after using my 100 energy a few minutes ago I now have just 8 energy but nothing I merged is still there, for example I used all my tree to make wands and brooms. Now just a couple of minutes later my tree is fully recharged and that takes around 2 and half hours to do so normally. The branches etc I merged to make better wands all gone
