stuttering / freezing on Hololens

hello

I'm using PUN to send a moving object position using a TransformView from a PC to a Hololens.

On the Hololens, the object freezes every .5 to 1 second, for about .5 to 1 second. It appears to just stop receiving any updates, and then resumes moving briefly before freezing again. For the brief moment it does update, it moves smoothly using the interpolation on the TransformView.

things i've tried:
- I've had issues previously with network messages (using regular sockets, not PUN) blocking the main thread on the Hololens, so as a test I placed several rotating cubes in the scene. They move smoothly.

- On another PC, the network transforms move smoothly, no issues.

- I've tried a sendRate of 3, 10(default), and 30, results are the same. I also reduced the number of objects down to just 1 TransformView and the results are the same, freezing every .5 to 1 second.

- Tested using both Cloud and local photon server.

Anyone have any experience with the Hololens and PUN or any ideas what might be causing the freezing? Are there any known issues with the way PUN processes messages on the Hololens that would cause these lags/freezes?

thanks!
