I made the update requested by the app for the controller and in the end I was asked to restart the controller. After restarting the control it didn't turn on anymore! How to solve?

Hi there. Thank you for reaching out and we're deeply sorry for the trouble. Can you please confirm if the remote controller shows any lights when you plug it into the charger? Could you please provide us a short video showing the remote controller when you turn it on? Please keep us posted. Thank you.
