Does anyone here have this?  
I tried this tonight and when I tilt the gimbal down, the second compass becomes yellow.
Is this normal or is it something to request a replacement drone?

I'm not sure how commonplace it is but I've seen a few other people report the same thing. Perhaps the best thing to do is contact DJI about it and let them make the call, at least if you're ok with getting back a refurbished Mavic in place of the one you have.

This video seems like a user uploaded before. If you have the same issue, I suggest sending it in and we will take care of it. Appreciate your understanding.

So, is this a real problem?  If I tilt the gimbal around 45º, the 2º compass will become yellow with a interference number around 365.
So far, I didn't have any problems with it. Do I need to worry about this?

This video is mine, I posted a couple weeks ago, still facing the problem.
Actually, there's a bunch of guys im my facebook group with the same problem.
DJI need to say something, this is not normal, it's a quality control issue IMHO.

I have the same problem, I acquired the drone 15 days ago and when moving the Gimbal accuses interference. What am I supposed to do? Is there any configuration or problem in Gimbal?
