Just a warning that if you haven't started postage editing yet (in the U.K ) then it might be wise to check on your overseas postage for listings that were running last year and reposted on the 6th May.
I've just sent this to support.
I've just been editing my postage rates and so far have come across four listings with no overseas postage. They were not over the 2kg weight limit so I couldn't understand why they were not offered overseas ?! The listing numbers are 154004469, 154004473, 154004429 & 154004441. Now I know I haven't taken off any international postage so I trawled back through the archives and found that all four items lost their international postage when I reposted them on the 6th May 2016. This means that I probably have another 30 or so listings out there with no overseas postage since last May.
I don't know if this has happened to other people or if it was just me but if it happened across the whole site on that day then a lot of overseas business could have been lost over the last year.
