Hello!
We have made our Shipping availability add-on compatible with CS-Cart 4.0.x. You can read the details and try demo here http://www.alt-team…ity-add-on.html
Best regards, Alt-team
Thanks!
We tried to contact them through both a ticket (our client's account) and through their form about whether they planned to release something for 4.0. Never heard a word after two attempts unfortunately.
And by this, we mean www.shippingkit.com about 4.0 comp.
