I integrated my UK eBay channel, but when I try to select eBay Germany as new channel, and put the same username as is under my UK one, it throws me an error saying I already have an account under that surname, saying that eBay accounts can only be integrated once.
But then how do I make a listing on a both German and UK eBay?
When using CBT accounts there is no need of integrating each site. UK integration will be enough. When creating listings for different sites you have an option what site to list on when you create a configurator.
Please keep in mind that this only applies to eBay. For Amazon you would need to integrate each site separately.
