BigSur Click on Dock App does not change to Space with App

Question

On catalina and earlier osx, I used to click on the app on dock to switch between spaces. This seems not to be working on BigSur.

Strangely, I couldn't find anything about this on the internet... I would expect more people to be complaining about it. If this is an isolated behaviour, please let me know.

Otherwise, anyone has any hints on how to get back to the previous behaviour?

Answer 1

This behaviour is toggled on a pref…

System Preferences > Mission Control > 'When switching to an application, switch to a Space with open windows for the application'
This needs to be on for the behaviour you desire.

It will fail if you have any app spread to more than one Space… but that always would. Spaces cannot handle multiple Spaces for a single app, that's not within design spec.
