Vive Trackers not working in 4.23

Hi,

I have trouble getting vive trackers to work with UE 4.23. I created a new VR base project and made a blueprint with a motioncontroller component as its base with uses the special_1 motionsource with refers to my tracker. In 4.21 this worked fine but now the component does not seem to get the tracker data.

Has anyone had this issue as well and found a solution or a clue to what is going on?

Thank you

Im also having this issue, hoping for a solution.
