Why won't it work with my SP3?!! Just got today, works fine with my Lumia 930, struggled with my Stream 7 - but i unplugged then retried and it works fine with that. But its driving me nuts that the SP3 wont connect!! See's it fine and is there in devices, but the connecting screen just times out. Waste of £48 right now. Downloaded the app and that suggest that tghe firmware is up to date, what next??
