Mac mail app: shows email header, but displays message saying there is no content
I have a resolution for this problem: you move the mail message from inbox to iCloud inbox and then back to the original gmail (in my case) inbox. This sequence results in the email message body being displayed.
What I don't understand is that given there is a 'work around' that works each time this occurs (i.e. there is a repeatable test case) why Apple staff have not isolated, and correct the problem so that we loyal users don't have to use a 'work around' to read our emails.
To the apple staff: thanks in advance to raising the priority of this issue and correcting the problem.
