This problem has been happening for a long time and it's really limiting my usage if the device. I upgraded everything to the latest firmware. However, I can't change any option through app like turning ac DC ports on and off or changing charge limit etc... tried both Bluetooth and wifi. I had some success after reset it multiple times by holding down the power for more than 15 seconds. Now none of it works. I had to turn on DC and ac port manually which is very inconvenient.
Is anybody running into the same issue? The app seems pretty buggy and not ready for the big league.
