UPDATE: sold another item - had same issue. STILL NOT RESOLVED. Last 3 of 4 sales = major problems resulting in potential loss of my item AND loss of $ from sale. ORIGINAL: App works mostly as described but they require you use their shipping labels & then don't update shipping status so buyer thinks item hasn't shipped. This happened to me twice in 3 sales. On latest OfferUp cancelled sale due to non-shipment after I mailed item! I've written customer service & am still waiting for a reply.
