Provide a way to Hide Sites from the Mobile Apps
The mobile SharePoint app shows every site. We have all kinds of "helper" sites that are not for use, and many solutions that are standalone sites that do not work in the mobile environment.
An example would be multiple sites for different documents, but how users are supposed to interact with them is a different site that is using a Search Results Web Part. We don't want users going to those direct sites for the documents.
There are lots of scenarios like this. I would propose a site-level setting that basically says "dont display this site in the SharePoint all"

This is must needed feature. We are implementing PowerApps using SharePoint as source, users are able edit the data without any restrictions in SharePoint Mobile app. This is BIG no.
