After assigning VPP application license and installing the app in device, I revoked the license while it was still installed. However, I was able to use the app even after 30 days. I think this app is not available in ASM(Apple School Manager) specification. Is this specification applied in ABM(Apple Business Manager)? I found this discription in ASM, but I couldn't find it in ABM. https://www.apple.com/au/education/docs/VPP_Education_Guide_EN_Oct13.pdf “When apps you’ve assigned are no longer needed by a user, you can revoke and reassign them to different users. The user gets a 30-day grace period to continue to use the app, save data, or buy a personal copy. ”
