When editing an attribute using set/edit, if the attribute in question is unset or otherwise None, the string "None" is prepended to the buffer.

I have added the link to the Snapweb page to my iPhone start screen. This way, it gets its own icon, so I don't have to open a browser and navigate to the Snapweb page manually.

However, when unlocking my iPhone and reopening the Snapweb app, I get this message and I have to close the app and reopen it. Is there a way to detect this and reconnect to the Snapserver ?
