@osedigital, can you please share which 3p cart plugin you're using so we could test it out? Thank you!

[osedigital]

@zlik, we are using "Ajax Shopping Cart by Amasty". Regards

We have a fix in #95. It will be released early next year. It does address the undefined TypeError, however, it does not solve for the 3p cart compatibility yet. We will consider reviewing Amasty's implementation and possibly refactoring our code next year. I'll close the issue for now, @osedigital, but the fix is unsatisfactory for you please feel free to comment or open a new one. Thank you.
