I am working on migrating mxds to Pro and I see that items are not maintained (Not sure if these items will never be supported in Pro or these items will be supported in later releases 2.3 and beyond). One such item is a grouped layout object. Some of the items in the layout group from ArcMap are brought into Pro but the layout group itself and some of the items in the group are not imported into Pro. I review the Import Notification in Pro and I see that Scale Text elements which are in the layout group were dropped but the Notification does not say that the layout group itself was dropped.
Does Pro recognize any layout groups or does it by default break up layout groups into their elementary objects? Or does Pro only break up layout groups if one of the elementary objects in the group is not supported in Pro?
