Has anyone else experienced the thumb control / joystick button to pop off?

One of the times I was using my Osmo I pulled it out of the case while inside of my car then walked away from the car and truned on the osmo and noticed the joystick cover was gone. I walked back and fourth between the car and where I discovered it was gone and couldnt find it. So I proceeded to the event I was on my way to and was able to still move the gimbal by the little nub inside the controller, which was a pain.

At the end of the day I get back to the car and look all over again and there it is on the floor mat of the car, I was so relieved I wasnt sure if I was going to be able to purchase a replacement piece or find something that would work.

Has anyone else had this happen or been able to replace it?

It just happened to me as well, and hoping that the only service center here in Norway has a spare to send me. I'm not going to send it in for repairs and having to wait weeks or months to have it repaired.
