Quick follow up… usually it’s best if you encounter any problems or errors with a theme, plugin, or even WordPress, it’s best to contact support first. That way, if anything needs fixing, it can get fixed right away. It’s odd you have js errors though because the theme gets reviewed by the WordPress theme review team and a theme does not get approved if even 1 error shows up, so it could be a plugin perhaps?
In your review, if you can, please provide details of the responsive not working and what js errors you had. I will then check this out on my test site and see if and what needs fixing.
