Zoom in/out in MacOS Calendar app not working

Hello,

I'm on a Macbook Air M3 running MacOS Sonoma 14.4.1.

The pinching gesture to zoom in / out on the Calendar app to change the view inside the app is not working. The gesture works fine on other apps (eg: browsers) but not on the Calendar app. Does anyone know why and could help out, please? I've been trying desperately to find solutions online, ran "killall Dock" in Terminal, looked for alternatives to do with a mouse, but nothing works. It's as if the Calendar app is 'locked' when it comes to zooming in or out of the view.

Note that I do *not* refer to the zoom in/out Accessibility feature, which literall zooms in/out the entire screen - that feature works just fine but is not what I am after.

Any help or tips would be much appreciated!

Thank you

Guillermo
