So... I was thinking about it. Before the update, the stream worked (on ShoSho) it was just stuttering a bunch...
The thing is, that may not have been Shosho's fault.
After going live directly from ZS, I noticed the same stuttering (even with a great wifi connection) if I streamed in basic quality.... the stuttering disappeared with higher quality settings, both better and best.
I never tried using better or best quality with ShoSho.
I wonder if the app was fine beforehand, and the stuttering wasn't due to shosho at all, but instead due to the ZS quality.
