Within the last 3 weeks our screen mirroring has not been working on our Samsung Smart TV. It used to work flawless less with our iPhone and ipad. We would used the screen mirror menu and click connect. Then a code would appear on the TV to enter. For the past 3 weeks when we select screen mirroring on the iPhone it will start sharing our music playlist but will not screen share! We have tried a lot of things. What has happened I feel it might be a software issue? Please help.
