We found out two issues that happened recently:
1) The Rooster Ally we were gifting for the Lunar New Year has been temporarily disabled from being granted. We are looking into the issue we had from PlayFab but there were a lot of API errors that might have bled into normal purchases.
Once we have this squared away, we will send off the Rooster again.
2) Purchasing not working. For over the last 24 hours purchases were not working properly on iOS. We believe we have fixed it on PLayFab now but if you are missing a purchase we can still check the receipt on your account, we just need your PlayFab ID.
This may have also caused a scary looking situation where you just finished a daily or weekly challenge and suddenly your gold appears to have been reduced to zero. That would be PlayFab sending gold to your account and then noticing that it isn't allowed to update gold so that means no one should have any gold... Or some sort of weird logic.
With PlayFab able to give out gold again, your old amount will magically appear again. Because Magic.
We're sorry about the hiccups.
