Google AI Studio UI issue: Device Preview / Reload App / Full Screen not working

Has anyone else run into a UI issue on Google AI Studio?

When I click Select Device Preview, Reload App, or Full Screen, nothing happens. No error message, no response — the buttons just fail silently.

This happens consistently for me and makes it hard to test prompts or layouts properly.

What I’ve tried:

Refreshing the page

Clearing cache

Different browsers

Incognito mode

Still no luck.

Curious if this is a known bug, a rollout issue, or something on my end. Would appreciate any insights or workarounds.
