I think everyone has left the clamp on at least a few times. I wouldn't make a habit out of it, but I wouldn't worry about it. I've done it a couple of times on my P3 and also once on the Mavic. As per the recommendations above, I agree 100%. Put some color on it. I've heard that there is a warning in the app to "remove gimbal clamp" if you forget but I don't recall ever seeing that. The fact that there is a warning would suggest that the Mavic knows the clamp is still on and wouldn't try to force the gimbal to fight it. Maybe. On a side note, I've noticed that it's easy to make contact with the ribbon cable when the clamp doesn't go on quite right. Be very careful not to damage the cable.
