A couple of days ago I successfully upgraded 10 of our nRF9160 devices using FOTA in nRF Cloud (MQTT). Several devices didn't upgrade and remained in status QUEUED. I've since been unable to get any further devices to upgrade. All queued devices are online (as reported by nRF Cloud) and are actively communicating with our own server via LTE-M. The devices are all the same hardware and software configuration. I've since cancelled/deleted/recreated the upgrades (a couple of times) but always with the same outcome. Several devices have remained in queued state for over 36 hours!
