Sage I know its been awhile - but I had this in my saved and I see that this didn't appear to be fully resolved. Based on my previous conversations with engineering, its either the redirects because of the localization or if its hosted with cloudflare, it may be blocking the crawler that would scrap the sitemap. You would need to disable the captcha for cloudflare if thats possible, and try importing again. Apologies for the delay here!
