You should upgrade or use an alternative browser. I am troubleshooting an issue where the PIA VPN app breaks the Mail Privacy Protection function on macOS Sequoia. Since I installed their app, my mails show "Your network preferences prevent content from loading privately" and you have to manually press the "Load Content Directly" button if you want to see your mail normally. It doesn't matter if the VPN app is closed and with the VPN tunnel inactive, just by having the PIA VPN app installed the problem arises.

For several years I had Cyberghost VPN and didn't encounter any issues, but in the past, I have seen other VPN apps like Express VPN conflict with Mail Privacy Protection too.

When the VPN is connected, the error message disappears as expected because Mail is using the VPN to load remote content.

By mistake, I pressed the X on the message "Remote content was loaded through your current VPN configuration" on the top of a mail message, and now this dialog isn't being displayed anymore. I am trying to get Mail to display this dialog again when it is using the VPN tunnel to display remote content. This will help me to troubleshoot the issue I am having, but haven't found any way to reset Apple Mail warning messages.

Does anyone know a way to make Apple Mail display again this message over mail messages that are being loaded through the VPN tunnel?

It is strange that Apple doesn't offer a way to get this message back, or a way to reset all warnings in Mail, so these kinds of messages can be displayed again if you have dismissed it once by clicking on the X.

I really appreciate your help with this.
