There are no issues if the device is unlocked and/or plugged into power, which led us to believe that the connection is dropped due to the system falling asleep. Connection to other things like Console.app log streaming seems to be dropped as well. By the way, these devices only have Wi-fi enabled and no cellular (no SIM attached). Could that also have something to do with this situation? And are there anything useful to pull out from the device logs that can help us with this? Thanks in advance,
