Polybuzz may not be working due to several common reasons including unstable internet connection, server outages, app glitches, or the app needing an update. Users often face issues like the app freezing, crashing, or failing to load messages when there is a network problem or when the Polybuzz servers are down temporarily. Restarting the app and device, clearing the app cache, updating the app to the latest version, or reinstalling it can often resolve these problems. Additionally, if many users report the same issue, it is likely related to a server-side problem which is typically resolved within hours to a few days. Checking for stable Wi-Fi or mobile data, and ensuring the app is updated are essential first steps to troubleshoot the issue.
