Hi @jumpgate85
A few EMO owners have discussed this in the past, you can see an older thread about it below:
This seems to happen due to the joints being a little too tight, it also happens to my EMOs as well.
Normally it should not pose a problem, but if you have any major issues or concerns, or if your EMO has trouble walking / dancing, etc. Do reach out to living.ai support for them to assist you further regarding this.
