Hi Rashida,
Ow wow. I never would have found that. So "Not Allowed (Inherited)" is not the same as emphatically Denied "Not Allowed" in the permissions for the "Public" group's acccess "Edit," "Edit State," and "Edit Own" for front-end editing of Page Bulider pages. I don't understand he difference, but that's ok. The main thing is it makes the difference we needed.
We thank you ever so much for finding that and updating our Staging site. I've now updated Production the same and removed the previous CSS rules we had in place to hide the buttons.
Deeply appreciative of your patience and persistence for us.
Kind regards.
