Mac Apps stopped installing

[ML_User]

We have a few Mac Apps configured to deploy via Jamf App Catalog.  They are all free apps.  They are Chrome, Google Drive, Google Chat, and Slack.  They are scoped to a Smart Group based on PreStage Enrollment. Everything was working fine up last night.  Now nothing installs. I tried to rescope the installations but they still would not install.  I created some App Store deployments scoped to both Groups and/or individual computer but they never install either.

Any assistance is appreciated.

Check your Volume Purchasing Token has not expired. That will stop them from installing. And an expired Apple Push certificate will give some issues too. These both have to be renewed each year.

OP stated the apps are from the Jamf app catalog, not Apple's VPP.

What are the Policy Logs and JAMF Logs saying?
