When I try to revise one of my listings or press "sell similar", it then comes up with the message "Looks like something is missing or invalid. Please fix any issues and try again". I'm very confused as my postage policy works fine when I sell an item from scratch rather than revising an existing listing or pressing "sell similar".
More information:
Delivery details If you wish to offer either flat or calculated postage, then you must select at least one domestic postage service, other than or in addition to Collection in person. Postage policy Flat: UK_CollectInPerson free, 2 working days (280834871015) (10 listings) Simple Delivery will override your domestic postage policy.
If anyone knows the issue, please let me know.
Thank you.

Hi @popshelf ,
Thank you for your post.
There is a ticket open with tech for that message regarding postage as it has been reported by other users. Can you share an example listing number or draft that you are getting this message for and I will add your account to the ticket.
Thank you,
Kat
