Some Windows 8.1 Modern Apps will not open

Question

Hi We have been using Windows 8 for 2 years, however since a recent migration to a global AD system multiple modern apps have stopped working. Mail, Store, Camera etc all work - however as an example Yammer, Weave, Facebook, Ebay etc all go to open, show
the splash screen then close (well they remain open on the side bar as a splash screen.
I ran the modern UI checker tool, all ok (initially it told me UAC was disabled, but it wasn't - but I clicked to correct this and its not reappeared.) it prompted me to update all my drivers - which I have done. I've checked folder permissions as per Article
ID: 2798317
Is there anything else I can check - it must be a group policy or rights change, but I can not find it. Additioanlly we are looking to widen the rollout of Windows 8 but unitll we resolve this there is no point.
Thanks

Hi,
Since it is joint in a domain computer, some Windows store Apps may be turned off by the  domain system administrator by group policy.
You should go to the domain system administrator for help or deal with this according to the following link if you have the permission:
here I give you the introduction about the Store related group policy settings:
