For some users, Revu for iPad crashes or won’t open after being deployed through a mobile device management (MDM) tool, such as Jamf or AirWatch. This is a known issue with Xamarin (a platform for building mobile apps) and MDM deployments on iPadOS 14.2 and above.
This issue will be resolved in an upcoming version of Revu for iPad, planned for release at the end of January 2021. In the meantime, your IT Admin can submit a support ticket for a temporary workaround.
