So, I reseted my phone today and I got a reminder to sign in so the continual experience between apps would work. Tough when I search about this feature I cant find anything. I remember last year or earlier this year they were talking about continual experience between uwp apps. But I found out that it did not work when i tried to see if for example the Maps app would sync between surface 3 and my phone with this feature. it might be that I havent connected the phone to the surface? But do I have to do that with Bluetooth or what? I have no clue how to this either and on the surface I can only see that it has connected to my Xbox. Anyone that could explain or send me a link about this feature?
