Content Type in Details Panel of SharePoint‎

Marcus_RowellI have the same problem. 2x tenancies I've checked so far. The new details pane now shows an icon that corresponds to the column type, there's a button to edit the list of columns in the form and Content Type is gone. Also with the Edit all form, it's gone too.

I've noticed for some time that when you click Show/hide columns in the header of a modern library, Content Type is not available as a choice, you have to use the classic Edit view to show it. Now it seems they've extended that to the choice of columns in the details pane.

This is immensely frustrating. I have customers asking me about it and there seems not to be a way to edit the content type of a file in a modern library any more without convoluted workarounds like Power Automate.
