Tried with iOS 2.5.0, 2.5.1; Android 2.5.0, Android Beta, all have me grounded. There is no option in the app to self certify. Doing the self certify using DJI's website has no effect. It will not take off.
I had this same issue with the Beta, but make sure you jump back on wifi or LTE and log back in to your DJI account under the app (Me) setting. It will then show you that the fight area is valid. Also make sure you use the SN under the beta app not the aircraft. Hope this helps!
