Did you check UpdatePilot for new firmware update? Iam thinking about gimbal new firmware. Can you please check? If you have a newer firmware alert - do not update!!!
I was thinking about this one

It should be available soon.
There is a setting in Hiden menu (you need to tap three dashes 5-6 times) how the drone should behave in such situations. In my opinion your drone acted properly. You may just set other RTH battery level to be sure that drone have enough power to return.
This should be done like a service call for all customers without any restritions if there is a guarantee or not. |This camera is not usable in that condition.
