When using the "new" UI (version 2) of Google Tag Manager, I cannot disable the preview/debug pane. It's appearing on every page of my web site whenever I'm logged into my Google Apps account.
I've deleted every cookie from a
*.google.com domain. As soon as I log back into my Gmail, the Tag Manager preview pane is back.
I've hunted through the Google Tag Manager tool, and I can't seem to find any way to turn off the preview mode. Even publishing the latest version doesn't do the trick.
In the "old" Tag Manager UI, when debug mode was enabled, a callout link would appear atop every GTM page allowing you to Exit debug mode. This does not appear to be possible in the "new" Tag Manager UI.
