Access to the Marketplace from the AppGallery client is controlled from the AppGallery server.
This feature requires AppGallery Mobile 188.8.131.52 or higher.
To disable Marketplace on AppGallery Mobile:
1. Log into AppGallery.
2. From the home page, click Collections on the menu bar.
3. Click "Create new collection" (as below) and enter a name for the collection, when prompted.
If the Collection already exists, simply open it for editing.
4. In the Collection's Settings tab, Turn on the "Disable Marketplace" switch.
5. Invite users and/or groups to share the Collection.
Devices that accept an invitation to share this collection will not (or no longer) have access to the Marketplace.
