Trying out

Thus I also downloaded the app for "private and faster" DNS queries. Then somehow I can no longer download attachments from GMail any more. [Edit: cannot save pictures from Discord chats either. But then Discord depends on a service of Google, so this may be a problem with Google only. Also tried downloading attachments using the Outlook app from my outlook email. It workes fine.]  flips a table I can see the text of emails fine and don't notice any website not accessible with on though. Once it is toggled off, downloading attachments work immediately. That's all I know. This is too involved for me to debug.
