Has anybody tried this fix.
we had issues with win 10 and store a while ago, i was playing with various reg settings with some success but not credible as issue would come and go... our win 10 device users, not many, just accept that they need to connect via lan to use the store but our rollout is about to go to 4000 devices, sorry for waffleing on but i now have to look into this again, i found this online which seems to have worked for some... i have yet to try as waiting for test device.
Open up gpedit on your local device
Computer Configuration/Administrator Templates/Network/Network Isolation
Enable Subnet Definitions are authoritative
Private Network ranges for Apps Enable
Then add your internal network subnet range IE 10.0.0.0/8
Restart your device and hopefully your windows store is working
i will be able to test next week so will keep posted...
