Why some emails very, very slow to open?
A recent issue is that my wife will mail out from Apple Mail and copy to me. When I get them and click on the mail a window opens to show it as usual but no content for 10 seconds or more. Finally it will appear if I wait long enough.
Other emails are not doing this, except occasionally. Most of the time it is with her email source.
What could be causing this? New to us.
We are both using Mojave.
