> This week we noticed that on cnmaestro cloud version, every epmp device with version 4.6,x seems to be offline. On network that we have remote access we managed to reconnect devices to maestro by updating them to latest 5.9 firmware. Do you know if will be a fix or we have to manual update every device to 5.9 in order to get them online to maestro again ?
