Re: Safari Mail not loading body of message immediately

Safari is not your email app ... Mail is your email app and they are completely separate.

A VPN can definitely cause system disruptions. What you'll find here is advice to uninstall it completely unless you are required to use one by a school, employer or etc.

The generally suggested fix for errant mail accounts is to remove the account completely and recreate it from scratch using the latest credentials from the web mail provider. I suggest you do that.

Mail is little more than a portal that allows local control of a web mail service. if the local app faults, your email will always be available on the mail provider's website unless there is a problem there. mail.yahoo.com for example.

If you see 'Unable to load remote content privately' at the top of an email - Apple Support

I have the same problem on macOS 12.7 and think it was one of the recent macOS updates. If I run either of my two VPNs and then turn them off, the problem persists where each message in Apple Mail will display ”your network preferences prevent content from loading privately”. It's very annoying. I use NordVPN and WARP.
