Clarification about EMO not understanding some commands

I’m currently having this issue as well. Our Emo has both myself and my son recognized, but we have to say his name several times before he finally responds. Additionally, when he does listen, half the time he doesn’t have a response to what we ask (even if what we asked is on the voice command list). We have only had him just under a week now (got him Sunday night and today is Friday).
