Compare the same app action on Wi-Fi and mobile data, then check the web version if one exists. If someone you know in another region can test safely, ask whether the same feature fails there. Match reports by time and symptom, not merely by service name.
A failure on one network may point to routing or local filtering; similar failures across several nearby networks make a regional service problem more plausible. Check official status and community reports, but label the conclusion as tentative until there is stronger evidence.
Include your broad region and time zone, not your precise location, in a public report.
