Workspace Settings

[JoeArchCap]

 Need to know what happens to existing PBI workspaces that are already established when we switch the Tenant Workspace Setting to specific security groups from Enable for the entire organization.  Will users lose access to their Workspace in they are not in an approved security group or will they  just not be able to create new workspaces.

HI @JoeArchCap,

I think this means these features will work for assigned group members, other members who work with these contents previously may not able to use these contents. (some of the shared contents may not disappear immediately, but users who not assign permissions standalone may not access them due to permission reasons)

I think you are mixing up app access and workspace access.  Is this on shared or premium capacity?
