Edit: This comment should be irrelevant cause I forgot I customised one of my keyboard shortcut on Mac setting.
Mistakes
Could you all try opening a new window of Anytype (cmd+n on Mac) and then open a space on the second window, then try using the keyboard shortcut again?
I believe the current functioning of ‘switch space’ is designed to work with switching windows/instances of Anytype, instead of switching space when space is not opened. In other words, the current keyboard shortcut behaves like alt+tab on Microsoft Windows…
If this is your scenario, this bug is technically by design and had occurred since the release of multi-space v.0.36.0. Sadly, I don’t think this shortcut has been actualised.
