My FULLSCREEN function does not work

[Chicago]

Hello. My FULL SCREEN function no longer works. When I select it, it makes a "ping" noise and the screen goes dark for a moment and then returns at the same size. I have signed out and also restarted my computer but neither solved the issue. If anyone has a solution, I'd be very thankful.

You can switch any of the layouts (except floating the thumbnail window) to full screen mode by double-clicking your Zoom window. You can exit full screen by double-clicking again or using the Esc key on your keyboard. Note: In older versions of macOS, click Meeting and Enter Fullscreen in the Top Menu bar

Regards,
James
