Why can't I add eBay as a sales channel on my platform?

Anybody know why I can’t add eBay to my Shopify?

I tried adding it to one of my test stores - no issue. To rule out the cache issue, have you tried another browser, particularly in the Incognito mode?

In case it doesn’t work, you can try opening a ticket with ebay app support
