Some SEOs are noticing that when you look at your sitemaps report in Bing Webmaster Tools, for some sitemaps, some are missing the Index Coverage button. I personally can see the same thing for some of the properties I have access to within Bing Webmaster Tools.
I spotted this a few days ago via Gaston Riera and Peter Nikolow on X who shared these screenshots of the sitemaps interface missing the index coverage button for some of the sitemaps that were submitted:
My guess is that there is not enough data for the index coverage report to show anything useful for these specific sitemap files? But I can be wrong.
Microsoft has not replied about this yet but I am curious what might be going on here.
Forum discussion at X.
Update: Fabrice from Bing later said on X, "Thanks, the team will review this quickly. Sitemaps that are a few days old and contain a sufficient number of URLs are indeed expected to have an index coverage report."
Update September 15, 2025 - it seems resolved now:
A follow up on this.

The index coverage has started reporting on the 9th of September.
Thank you very much @facan for jumping in quick on this matter
