I recently purchased an AGRAS T40. After calibrating all systems I still am not permitted to take off. The warning says, takeoff prohbited by app, go back to home screen for more information. The issue is there is no more information on the home screen. The only other warning is take-off weight exceeded. I have tried recalibrating the tare, weight sensors, changing the payload, entirely removing it. The drone simply won't take off, any thoughts?

Same issue here, any solutions found?

Any solution to this issue?

Same issue. DJI, please pipe in. Reset sensors to 0 with empty tank. Re-seated all connections.

I have the same problem.  I downloaded firmware and uploaded it again, I did all the calibrations but the same error still appears.  Has anyone found the solution?

Same issue here but I turned off all safety features, then I crashed it into a tree. 100% pilot error. The last thing I did was turn the remote on and off and it worked. All good!
