This has been the case as long as I can remember, but when I forward emails with images, the images don’t get forwarded. Of course, I’m talking about the default mail app.
Instead, I get a blank box where the image should be located.
This has always been a sort of minor quibble, but today I had to forward an email with images, and I had to go into the Fastmail app to do it.
Searching the Internet, I found only Apple Discussions (discussions.apple.com) of others complaining about the same issue.
Certainly, I must be missing a setting. I can’t believe this issue has been around this long.
