Hi,
the only thing eBay told us to do is to change the name of the “USPS Parcel Select” to “USPS Ground Advantage”. We did this and already uploaded the new eBay-metadata file for GarageSale.
GarageSale will pick up this change after it is restarted (and if you have a working internet connection).
Please tell me if you still get any warnings or errors when using the service with the new name.
Thanks,
Paul
