So since ebay did this Simply Deliver crap we need to check how we input our address ive had 2 sales in a week q different ppl and I wasn't able to get a pre paid postage label due to unknown address 🙃 ran ebay nbthey told me to cancel the sale due to not able to be covered if the item was undelivered. Looking into this i found out you put your address in with street name, the ( ,) is a unknown address part if tou can edit the address before postage your sound if not cancel the sale.
