Like many others, I was eager to update Unity to the newly released 2017.2 version and get started with HoloLens and WMR development there. Unfortunately I’ve a lot of issues getting my applications to work properly with the new editor and the latest MRTK. Input by air tap and gaze just doesn’t seem to work for some reason. The MRTK home page states there is a bug waiting to be fixed in the editor and advises to wait with the 2017.2 update until it’s fixed. Maybe you want to wait too.
