There are a few ways you can push the updates. Here, this iOS app distribution guide will be of help. Hexnode MDM will regularly scan the mandatory apps list to see if any updates are available in App store and will automatically push the updates if any. As for enterprise apps, if a new version is uploaded in the portal, it will automatically be pushed to the assigned devices.
On Supervised devices, the updates would mostly happen silently. Here’s another piece of help on how you can ensure the updates are pushed without any user intervention.
Thanks and regards
