Is anyone else having problems sending pictures in HEIF instead of JPEG? I have an iPhone 7 with 11.0.3 sending an HEIF imageto someone with an iPhone SE (also tried with another 7). All of my and their devices are on iOS 11 or High Sierra. The picture is saved as an HEIF image in Photos on my Mac but shows up as JPEG when I view the file type in messages on my Mac. Just to clarify: Taking picture on my iPhone 7 -> sending it to an iOS 11 iPhone SE (and 7) -> I check the image file type on messages on my Mac and it says JPEG.
