The error when updating system apps for Windows 10 Mobile has been fixed
Microsoft fixes the issue with the Store for some phones
Windows 10 Mobile preview build 10586 is now available for Insiders on the Fast and Slow Rings, and of course, for all customers who have just bought the Lumia 950 or Lumia 950 XL.
While this build is pretty reliable and stable, many Lumia phones have had an annoying problem with the Store – some apps refusing to update. Around 10 apps, most of them system apps like Touch, Glance, Extras, were stuck in the Store with the same update error – 0x803F8006.
Now it seems that everything is fine and you can finally update these stuck apps in the Store.
