This is happening with 3 free apps. And yes, the app was deployed today to other devices, updated on some other devices from an older version (which is what we're doing here, updating these 3 free apps to the latest version), and we can even uninstall and reinstall on other devices (but not this device)
I’m getting the same error code and for example WhatsApp is showing 50/50 licenses available, even though we have it installed on devices. I did a forced VPP sync and still no dice, verified the push certs etc are still within date and they have plenty of time left. At this point I cannot upgrade apps on phones that have apps installed and are out of date. What could be causing this?
