In general, the term "delivered" in the PushPanda backend refers to a successfully sent and forwarded notification.
Below, you find possible solutions for situations where notifications are "delivered" but are not visible on subscribers' devices or your website.
Web push notifications are blocked in the settings
Check your browser settings on desktop or app settings on mobile:
Windows Notification Settings
a. Disable the focus assist
b. Check Settings > Notifications & Actions > Enable Receive notifications from apps and other senders. Make sure your website and browser are also enabled. More info here.
macOS Notification Settings
System Preferences > Notifications > Chrome or alternative browser → Allow notifications option enabled.
System Preferences > Notifications > Do Not Disturb & Sleep → not active or within the time that notifications are allowed.
Android notification settings
Settings > Apps > Chrome (or browser of your choice) > Notifications → desired website "Enabled".
Network problems - No internet
Devices must be online to receive web push notifications. If switched off, flight mode, unstable or no internet connection, web push notifications cannot be displayed until a proper connection is established. The time that the Google and Apple servers wait for an internet connection can be set with the Time To Live (TTL) parameter (default: 3 days).
Since the connection to the Apple or Google servers may have been closed, checking the network and the WiFi is essential. Sometimes it can help to deactivate and reactivate the Internet connection.
No current subscription
Make sure the device is subscribed to web push notifications.
No subscriber to the segment or interest was addressed.
Check the segment to which the web push notification was sent and make sure it is set up correctly. Sometimes an incorrect filter is added to the segment that excludes specific devices.
Browser is closed
Some browsers do not receive web push notifications if they are not running. Click here, for more information.
Deleting browser data
If cookies, data and/or browser history are deleted, the browser will no longer receive notifications, and the website will need to be revisited to log back in.
Browser does not support web push notifications
Users must subscribe to notifications on their desktop to receive notifications. Furthermore, it must be a browser that supports web push notifications.
