I followed this tutorial https://learn.microsoft.com/en-us/training/modules/learn-mrtk-tutorials/1-1-introduction and did every step. But when I run it on the HoloLens, I don't see anything.
Build configurations are as in the tutorial, HoloLens2 is in Developer mode and has been paired before. Tools are as in https://learn.microsoft.com/de-de/windows/mixed-reality/develop/install-the-tools?tabs=unity I am building the app over WIFI. When the app starts on HoloLens, mesh appears for a moment and I get a question asking if it is allowed to use on my microphone. "Build with Unity" or similar does not appear, and no objects either. I see "nothing". What could be the problem?
I use: Unity 2021.1.20f MRTK v1.0.2206. Preview (from Microsoft Download Center)
It was actually the wrong Unity version. I am now using Unity 2020.3.4 and I can see and move the objects.
