I'm not sure if my explanation is understandable.
Looks like my mouth doesn't move.
In the straight face my mouth can open and close normally
But when turning to the left or right and including various directions
The mouth that moves along is only the mouth closed.
The open mouth is still in the upright position as usual. How should I fix it?
Please anyone who knows how to fix it, please help me.
The video I recorded was where the problem occurred.https://1th.me/gkL0h
