I used to be able to switch/toggle through open windows of a particular application using ⌘ ` until the latest MacOS upgrade. Now it no longer works. Is it just me?
Just tried it on Sonoma, Mac Book Pro 16 M1 Max, and works... It was not something i knew about before, so thanks for the heads up on it, but it is working... At least on Edge browser.
Check if you have Stage Manager enabled by accident, it slightly changes how window switching works.
