Search works on mobile but not web: isolate the surface

Compare the same public query on mobile and web while signed into the same account, if safe to do so. Record app and browser versions, local time with timezone, and whether the web page fails to load, shows stale results, or merely lacks suggestions. Test a private browser window to separate an extension or cached state from the service, but do not treat that test as proof of the cause. Share only non-sensitive terms and a cropped screenshot. The report should identify the failing interface and the one that still works.
