hey guys, for some times now, my drone camera do not see my ipad, telling me camera senor error. what should i do please i need help thanks

You have installed the latest firmware version for both aircraft and remote, right? The APP is up to date as well?
Did you tried to restart the drone, it did not help?
How long you've owned it? no crash or hard landing, right?
If the error persists after you tried the basic troubleshooting, it needs to be sent in, you can contact the dealer for help firstly, or send an e-mail to support@dji.com, thanks.
