I have powered on my device and the blue led starts blinking. I have used my laptop and my android charger for the power-up process. I have downloaded the Bolt IoT app and followed the setup process on my mobile. After following the setup process, the blue led is stable and the green led is also on. But I cannot see my device in Bolt IoT Android app and also it is mentioned that it is registered with some-other ID
