Transfer moments to camera roll
I am using an iPhone 7+ 128gb running iOS 10.2(14C92).
My issue is whenever I want to send a photo to someone I can't choose it from camera roll, for example, I want to send my friends an old photo. This old photo is not in my camera roll, but it is in my moments. What I have to do is find this old photo, and either duplicate it and then choose it from my camera roll, or simply use the share option which I really do not like. This is because I cannot choose moments in the album chooser, since moments is apparently not an album which I can choose. I have all these photos from my moments because I used to have an iPhone 5s, so my photos app on my mac is full of these photos, and now they're in moments in my iphone 7
So, i'd like to transfer all my photos from moments to my camera roll so i don't have to do this process... Please help! It's really bugging me!
I've tried syncing all of the photos that are on my photos app into my iphone via iTunes, and then duplicating these photos so they appear in my camera roll, then going into my itunes and unsyncing all my photos. The problem with this is that the duplicated photos are not in chronological order. This is pretty ridiculous in my opinion, how was apple not thought of this. Help is greatly appreciated.
