I left positive feedback to a seller as it wasn't their fault that my recent purchase never arrived due to problems with simple delivery labels (Evri). The feedback has disappeared however. I had mentioned the item didn't arrive due to simple delivery. Is ebay removing positive feedback that negatively reflects the platform? I opened a case to get my refund where ebay arbitrate between buyer and seller, and no mention is made of themselves as the third party in the transaction and therefore the cause of the problem.
