You might have noticed that Google Tag Manager overview got a new look. Apparently these UI updates are happening now because of the previously announced GTM + Google Tag integration coming in September 2026.

Here's how the GTM workspace overview has changed:

• Collapsible left nav

◦ Some features (like Triggers and Variables) are now hidden behind 'Show more' in the left nav

• Welcome cards at the top
• Google Tags have flowchart visualization
• You can sort the table by clicking each column header

I checked on a bunch of GTM containers we have access to and these changes are only in some of them so it's still rolling out.
