Hi, we're sorry to know about this situation. I would like to ask if you encounter any prompt message in the application during the activation process? What is the model of your mobile device that you use to activate this Inspire 2? I would recommend updating the firmware of your Inspire 2 and try to reactivate again. The link below will allow you to download the DJI Assistant 2 on your computer for a firmware update. You may refer to the video tutorials below for activating and updating the firmware of your Inspire 2. Please keep us posted on the latest progress. Thank you for continued support.
