Connected the Onyx+ with Haptics Connect. Increased the speed setting well above 10, and verified Hello Strokes was on (did get hello strokes on the Onyx+). Still same issue as before. The player tab on the Haptics Connect shows the video on the DeoVR app at the correct time stamp and DeoVR sees the Haptics Connect as connected in the side menu of the video.
Edit: Also in Manual tab of the Haptics Connect the Onyx+ works just fine so the Onyx+ to Haptics Connect connection isn't an issue.
Just to try to narrow down the issue, I connected the Power Blow in Haptics Connect and also no action during the video, even though it works in DeoVR when connected directly. Don't know if it is an issue of PowerBlow not being properly supported or not.
