There are a few other places we would like to direct you to for support, both from Microsoft and from the community.
The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.
For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality.
If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers, or in our Microsoft Tech Communities forums at https://techcommunity.microsoft.com/t5/mixed-reality/ct-p/MicrosoftMixedReality.
And always feel free to hit us up on Twitter @MxdRealityDev.
Store app disappeared on HoloLens
I reset HoloLens, and there's no more "Store" app.
Only 6 apps appear in total - Edge, Feedback hub, Settings, Photos, Holograms and Learn Gestures.
I saw in other post updating device solves this issue.
So I tried to update the device in Settings>Device Update, yet I keep getting error installing updates (0x80070002)
FYI, I turned on developer mode and device portal.
