Downward ultrasonics stopped working?

[mechrock]

Ever since the Update to enable support for the DJI googles my ultrasonic sensors stopped working.
I found this out the hard way by smacking my Mavic into a table when trying to land. Luckily I have legs so it didn't crush the gimble. Any one have any suggestions?

I tried updating to .800 to see if that would fix it, no go.
I calibrated the VPS as well, but that appears to be just for the cameras.
Reset didn't seem to work through DJI assistant.
Disabling and re-enabling through settings in DJI go app doesn't seem to work either.

Anything else I can try?

Did you try enabling the Landing Protection setting in DJI GO?

Thanks, I have already tried disabling and re-enabling this setting. I used to be able to put my hand under the Mavic and it rise up, now it just sits there.

Same happened to me, it gave me a "ultrasonic module" error after an update. I have to be very careful when landing.
