I am using Owebia Shipping extension for Magento 2. I entered a rule in that shipping method which says if the weight is
> 0 the shipping will be $5.
This always gave me the "No shipping method available" message in the checkout. So I changed the rule to
>= 0 and the $5 were shown.
I checked my products and they all have a weight > 0 in kilogram. I also tried other shipping methods / extensions, it all comes down to the same problem - weight is always 0 in my shop even though the products have a weight assigned.
Any idea what might be the problem here?
