PeterGriffin456 Yes, the bluetooth has improved a lot, though there is 1 small bug we are aware off, yet no one up untill now reported on it. So I guess it doesn't happen often. It's also fixed in the upcoming update.
The Handy uses WiFi and you don't need a 2nd device for it to connect to.
The order in which you connect the Launch still does matter. Best is (imo) connect SLRinteractive with Launch, then start SLR/Deo . Log in so the player connects to SLRinteractive. Then load your video/stream.
Sometimes you can fix bad connection by changing the source stream and resolution. If playing local or DLNA, you must load a different video entirely. It's also not a guaranteed fix.
If still not fixed you have to start all over. Shut down launch, exit player...
We have a possible solution in the works for this, it's unrelated to the bug I mentioned earlier.
