If a user is a member of multiple groups, he/she will receive all settings (Policies, Profiles, Apps, Managed Configurations (for iOS or Android) or Documents (iOS) ) assigned to these groups.
Example:
User 11 is a member of the Sales and Marketing groups.
The Marketing group is assigned the ezeep Blue app, and the Sales group is assigned the Gmail app.
Since User 11 is a member of both groups, User 11's Android devices receive both apps.
The same applies to the assignment of profiles, managed configurations and documents. When assigning policies, there are some specifics that are essential to keep in mind. You can find detailed information on this in our help article Special conditions when assigning multiple policies.
