Content in Mail slow to display
Mail loads, but does not show the content in the viewer window. The preview shows, so the content is loaded and there. If I hit forward or reply, the content will even show in a new email. The header is there, but the content window remains empty, often for several minutes or more, and then it will suddenly appear And then sometimes it works right away. Sometimes the content will temporarily disappear even on messages that have been opened before, but when I go to look at them again, the content is not visible.
No problems with mail (same accounts) on other devices, so this is not an internet or mail server problem. It is a Mail problem.
I've seen this raised many times in forums, but have yet to see a solution.
