Can't run SharingTest scene from HoloToolkit-Test on emulator
I compiled the sample and put to my HoloLens where is working fine, but when I tried to do the same on emulator I got "Found anchor, ready to export" message and later I have hundreds of "Failed to upload anchor, trying again..." messages. 
I tried to debug ImportExportAnchorManager script and I found that problem is in ExportComplete method where there is a check for exportingAnchorBytes.Count. In my case it has always 310 bytes that that is too low for MinTrustworthySerializedAnchorDataSize (set to 100000).
Anyone had similar issue? I didn't change anything on this project so it should work just OOTB. Am I missing something?
I was able to repro this on another machine both with Unity 5.6.3p2, HoloToolkit 1.5.7 and emulator v10.0.14393.1358. I tried many rooms but it always is 310.
