Following your suggestion ... I created a new site, (not sub site), using the Enterprise\Document-Center template. I uploaded two files for an added visual of which view (classic/modern) I was in. The new site is in the CLASSIC view.
Let me clarify what we are talking about.
This is NOT what I'm referring to ... The SITES page on the waffle menu, got changed and renamed to SHAREPOINT. I'm good here.
This is NOT what I'm referring to ... The SITES CONTENTS view changed. I'm good here.
This IS what I'm referring to ... There is the MODERN document library that has the command bar instead of the ribbon. I do NOT have this. While I could go into each library and change the view for that library only, that is not practical.
I do understand updates are constantly occurring. My concern is that one day everyone in my tenant will see the MODERN document view and I will have had no notice it was coming, and because I don't see it now, I cannot prepare for this change. I have three of us in the tenant setup as FIRST RELEASE. None of us have the MODERN document view.
