@nkgrzegorzewicz Was it fixed in opera 117.0.5408.197? Or will it be fixed later? Because I still observe the same behaviour. Buttons in notification don't work. It just opens empty tab. Usually if it was timer notification showed up with start timer button, I clicked button, it correctly started timer in extension. Now just emty tab and no effect on extension. Doesn't work for multiple extensions such as pomodoro, timer, some message extensions don't open the message, etc
