Hello everyone.

We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.

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.

The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.

On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.

So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. 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. And always feel free to hit us up on Twitter @MxdRealityDev.

MR and Azure 303: Natural language understanding (LUIS) - Issue

Hi, I'm trying to run the MR and Azure 303 sample from the Mixed Reality Academy on a HoloLens. The application builds and starts running on the HoloLens, the mic is recognized, but whenever I say sentences declared as utterances nothing happens. I'm getting the following in the output window:

Windows Mixed Reality spatial locatability state changed to 3.

Failed to get spatial stage statics - can't retrieve or interact with boundaries! Error code: '0x80040154'.

(Filename: C:\buildslave\unity\build\Runtime/VR/HoloLens/StageRoot.cpp Line: 20)

Any ideas what could be going wrong and why the voice commands are not being processed?
