Device not responding to MDM actions

out of 37 devices, 7 are inactive( al are ios ). We have checked one of the devices and the broadcast message was sent successful. Additionally, Cx confirmed that the location history is shown properly. We restarted the device, checked the date and time, and found it to be correct. We also switched to a different network, but that doesn't change anything. The sync from the Hexnode app was successful. We reinstalled the MDM profile, yet it doesn't change anything. We renewed the APNs once and checked, but the scan device action remains pending.
