Hello
I have a strange issue with multiple select attribute.....
I have created a multiple select attribute and filled with around 20 values.
If I update a product, the product and its attribute are updated correctly .
If I update more products all together selecting various SKU in the catalog list the attribute for the multiple select is not updated.
Can you please check by your side if this behavior happen to you too and let me know before to proceed opening a ticket for this.
Thank you
