Despite my window sizing issues for Blend on my netbook, it still worked. That's fixed, by the way. Suddenly, about a week ago, Blend stopped working. I'd suspect Win10, but it's not connecting to my Nexus 7, either. I have a friend in another state who's experiencing the same thing with a Mac -- not the person whose thread I commented in.
The Nexus tablet says the Blend connection is unavailable. Win10 shows connecting, then disconnecting. I suspect the two look different only because of OS differences. I'm thinking the phone end got glitched somehow.
I'm wondering if a complete wipe might help. But, before I take such a drastic step, are there otrher settings besides allowing connections and having specific device connections on that I might have accidentally changed?
