New postage costs hasn't updated on simple delivery

[briggsyd]

Yesterday, postage prices went up. It's allowed me to add new listing's under the new postage prices but it's not updating the new prices on existing listing's. I've been through every listing on the app and mobile desktop and there's no option. It's just showing £3.38 and not £3.55. Surely my buyer will face postage fees if they buy and not enough is paid. What do I do?

You do nothing. If it’s on SD, you just use the issued label as before. The price ebay sets is a contract price so to speak. If the parcel is within the dimensions of the service, then you continue as you were. The price ebay charges for delivery is not always the same as the price charged if an individual books and pays for the service.
