Mac Mails: "Your network preferences prevent content from loading privately."
On my Mac Studio running iOS 13.5 and no AV app, each of my Apple Mail messages from my various email accounts (i.e. Apple, Gmail, etc.) suddenly stopped displaying graphics. iCloud system status is all green. Never happened before tonight. What triggered this? I've read about turning off "Protect Mail Activity" and keeping "Hide IP Address" in my Mail Settings, and some other potential solutions, but they have not solved the problem. What is the cause of this? Is it a bug? How do I resolve this without compromising my computer's security and without having to hit the "Load Content Directly" button for each email?
Thanks!
