Since grouping by 'Content Type' is apparently not supported, I'm creating a 'work around' Flow on a list to update a simple text field 'ContentType' with the 'Content Type name".
Setting it to fire on new records is easy using modified=created, however, using the technique "Get changes for an item or a file (properties only)" doesn't seem to provide the column in a condition "Has Columns Changed:.........". All other fields are there EXCEPT "Content Type name", "Content Type Id" etc.
So Content Types are a big thing in SharePoint, but you can't group on them and you can't tell using standard techniques if it's changed or not.
Am I missing something? Is there some other technique my research has not revealed?
So I ran the flow and because I can't insert the clause in the flow that checks if Has Changed: "Content Type name" the flow keeps looping and looping.
