It looks like there's a nasty bug breaking in-app purchases (IAP) across the Windows Store on all platforms. A number of app developers have taken to Microsoft's developer support forums complaining that purchase tokens aren't being recognized, resulting in users losing access to previously purchased IAPs. And the problem looks to be pretty widespread, with well-known 6tag developer Rudy Huyn explaining that it occurs across all platforms:
"This bug occurs on ALL Windows (phone, 8.1, 10, mobile, etc…) and with ALL apps, so please, don't blame app developers, it's not our fault"
Unfortunately, in looking at the developer complaints on the support forums, it doesn't look as if the problem has been publicly addressed by Microsoft, but hopefully a fix isn't too far off.
