I understand the seller can only select one category for each item (which i find quite silly)
Although when i go in and manually add additional categories, they go away once the seller makes an update to the product. I need a work around for this, because it does not make sense to me why a seller would only put their items in one category in a large marketplace? My sellers need to put their items in multiple categories.
I have forward this issue to our developer team. Hope they will fix this issue in our next update. Currently we have lots of work in our queue. We are completing task one after another. So it is need adequate time to add this feature. Therefore, please keep patience.
