Does anyone use Visio Web Editing with any regularity?
I see in the information from Microsoft that locking groups is not supported, there are regular updates to Visio Web so I wonder if that still is the case.
Ungrouping shapes is pretty catastrophic for shape functionality so LockGroup is a pretty important protection, hopefully they have finally added it.
