December update slow network performance

After the decemebr update i have difficulties starting playing movies from my win10 device with vero 4k+. When I start a video it shows a few frames and then freezes. After sometime the movie does starts playing.

How can I move back to previous release to confirmof it is dec release?

You can reinstall from if you wish to downgrade.

But then i need to reconfig everything. Just checking server performance and network speeds are ok. It just freezes and then starts playing. Network when the freeze happens shows around 32mbps.

Ok i just saw that disk speed jumps to100% explaining the freeze. Might not be network speed. But why to start playing i have 100% disk usage. Might not be vero related.
