Resize photo via Mail not working
I need to resize a photo from Camera Roll, and I see a lot of advice on the web simply to send it to myself via Mail. Supposedly, Mail will offer me a choice among several sizes at which to send it. That would be all I need, but Mail is not doing that for me; it simply sends the photo as is.
I have tried this on my iPad2 (iOS 9.3.5) and my wife’s iPad Air (iOS 11.2.5), with the same result on both. I have looked in Mail’s settings, but found nothing promising.
What am I missing?
