I am using AirPlay and the image on the TV will not rotate. The image on my phone is in landscape. The image on my tv is in portrait but sideways. Rotate lock is turned OFF on my phone.

Good afternoon Bacon_is_delicious,

Welcome to the Apple Support Communities!

I understand an image on your iPhone in landscape mode is not showing the same orientation on your Apple TV. Is this issue happening with one particular image or with all photos and videos? Try restarting your iPhone and your Apple TV to refresh the connection.

Take care.
