Hey everybody!!
I don’t fly much in sport mode but I’ve never noticed this before. The gimbal jumps around when flying in sport mode  Is this normal?

Nope, that's not normal. Might wanna search similar threads for solution

Could you please provide a short video about this issue so I can look into it?

Hello. I have a similar problem. Here's a short video. There was a little wind but nothing crazy. Is that normal?!
