Gimble Problem on new firmware?

[GavieboyDji]

Is anyone else with the Mavic Pro 1 having gimble tilting problems on the new firmware using stock up to date go4 app. When I yaw left or right my gimble is tilting and hunting won't stay level.
Have anyone had this problem and found a fix.
I'm just charging my batteries back up from flying tonight and then I'm going to go back one firmware.
Thanks

Firmware 400 and 500 are strictly identical for aircraft and remote so if that's what you're comparing it can't be that.
