I am not able to set page properties from the 'Page details' button on a modern page.
I've created two columns in the Site Page library, one 'choice' and one 'single link of text', and they are both added to the Site Pages content type. They also appear under Page Details but I can't make any choices.
Same issue in two seperate tenants.
A known problem for anyone? Or is this a disabled feature for the time being?
