Will Not Be Addressed
The development team has considered the issue or request and concluded it will not be addressed. The issue's Additional Information section may contain further explanation.
This is as designed. The webmap needs to also be shared with the organization. The basemap gallery setting is something that applies to all users of the organization and they have to be able to see that webmap in order to use it. Hence, it needs to be shared at least to the organization as well as to the designated basemap group.
