Apple mail does not show text or fotos

Since I have installed the latest Norton update, Ih can’t see neither text nor fotos in apple mail. Thank you for your support. Kind regards, Martin

As Apple Mail sounds like you are using a Mac, I’ve had your thread moved to the Mac board for better exposure to Mac users.

I have also lost the ability to view graphics / images within mail since updating Norton. So, how to I undo whatever these new Norton settings are so that I can once again read my emails properly? Best wishes, Andrew
