GarageSale 7.0.9 is the latest version. It’s available through the built-in updater.
That’s correct, GarageSale 7.0.8 and higher only insert https content. However, you maybe started listings that you “imported from My eBay”.
To make sure there’re no additional links or http content in your item description you can use the “Repair Image Links” command from the “Listing” menu. This command is especially useful if you imported listings from “My eBay”, which contain image links and http image URLs in the description.
(How to make your listings ready for eBay's new policies (https, links, active content) - #3)
Yes, but you should check if there’s non-compliant content in your listing, e.g. item description. For further details, plaese check the link above.
Revising through the eBay website shouldn’t be necessary, if you use the latest GarageSale version and make sure taht you don’t use non-compliant content.
