I got an MU model too. There's a petition online to add Airplay 2 and Apple TV to our models. It's here: https://www.change.org/p/samsung-bring-airplay-2-itunes-and-homekit-to-2017-samsung-premium-oled-tvs
I really hope they add these features with a firmware update
Why only oled tv ?
Do not update.
Current version much better
I also have 55mu7000. Now i have 1270.3 on ota. Should i update ? Have more people difficulties with this update ?
