:D :DI have also added the new - update - version (c?) - that did not fix my issue.
I also created a new test string and it did not add to the cart.
you can see that it does not add to the cart - and does not appear on the invoices either.
But because it does not recognise the string attributes then when I change a single attribute it just adds to the original. It needs to add as a new product to the cart. Same sku but different colours.
See images of my set ups.
