This is so frustrating. I use a Pure Jongo over Bluetooth to stream music to my AV receiver. It had been a bit of a faff to make it work before, but I had found a method and it was reliable. I hadn't used it for a while and thought I was going a bit crazy when I couldn't make it work. Rolling back the driver has helped, but I have to be fast to get music playing on it otherwise it disconnects.
It works fine from my Apple devices, both with and without the dedicated Pure App.
Microsoft - please fix!
