It seems to me that the steps above would have a pretty major impact on an organization. Is there any evidence that it would make a difference?
For what it's worth, our organization with about 10 users is seeing the same issue. Opening a Teams-based PowerPoint file in the desktop app (at least for macOS) works fine with I am the only user. It's barely acceptable when one other user is in the same document. (And that user is Windows based.). By the time a third user (this time Web-based) enters the document, it is impossible to make any edit without a 30 second delay.
I frankly can't understand how credentials would be responsible for this.
