SKU missing on App

[trackin-909]

Today I find it impossible, after latest update, to see the box for SKU number on the app, please can someone advise.  I have to actually go onto the eBay main website to enter the sku number.  Thank you

Private sellers don't need SKU, as they don't hold stock.

If you buy to sell, you should upgrade to business seller.
