Why is installed app inventory outdated or incorrect?

After installing new apps or app updates to a device, the installed apps display may show outdated information. The new app installed may not display. If an app update is installed, the old app version may still display. This information may appear incorrectly for up to an hour after the change occurs on the device.

This information is sometimes outdated due to the design of iOS. iOS does not notify SimpleMDM when it successfully installs or updates an app. In order for SimpleMDM to know the current app inventory of a device, it must check in with the device on a regular basis. Checking in excessively can cause a noticeable drain of the battery, so SimpleMDM must balance data freshness with good battery life.
