You can batch push the app to a whole bunch of devices at the same time. Just create a group and add all those devices. Now you create a policy, and in the Mandatory apps sections, you add the selected app. You can add multiple apps here. Assign the policy to the group you had created and the selected app/apps will be pushed to all the devices.
Let’s say you have your company app on both iOS and Android platforms. You don’t have to group the devices based on their platform to push the apps. That’s the beauty of it! You can add all the devices to one group, configure a single policy, select the apps across each platform and add it to the mandatory apps list. Apps will be automatically pushed to devices on the respective platforms.
