Enabling push notifications
Look for "Enable push notifications" in the app. When you tap it, a few things get checked in order, and each has its own message if it fails:
| Message | Cause | Fix |
|---|---|---|
| This browser does not support push notifications | Your browser doesn't support the required web APIs | Use a modern browser (recent Chrome, Firefox, Edge, or Safari) |
| On iOS, add the app to your Home Screen: Share → Add to Home Screen | On iPhone/iPad, Safari only allows push for sites added to the Home Screen | Open the site in Safari, tap Share, then "Add to Home Screen", and open the app from there before enabling push |
| Push notifications are blocked in your browser | You (or the browser) previously denied the permission prompt | Re-enable notification permission for the site in your browser's site settings |
| VAPID key is not configured on the server | Server-side configuration issue | Not something you can fix — report it to a manager/admin |
Why notifications silently stop arriving later
This is the most common long-term issue, and it doesn't show any error at all: if your subscription expires (browser data cleared, app reinstalled, long time without opening the app), the server detects that the push service rejected the last message and automatically turns off that subscription in the background. You won't see a warning — notifications just quietly stop.
Fix: open the app and tap "Enable push notifications" again. This creates a fresh subscription and notifications resume immediately.
If notifications still don't come back after re-enabling, check that notification permission for the site is actually allowed in your browser or phone settings — the app can't force it back on for you.
