Siberian PWA FCM Web Push notification limitations:

  • You can’t send individual or scheduled push notifications in PWA.
  • Firebase Web Push is only works in Android Chrome, Android Firefox & Desktop Chrome.
  • iOS doesn’t support this web push functionality yet.
  • You can’t open internal pages of an app using click action link.

Notes:

  • The push notification request access prompt can only be shown once as this feature is not application-specific but depends on the vendor/device/browser the application is being used on.
  • If you have subscribed push notification successfully then it will display the toast message saying that “Successfully subscribed”.
  • Once the notification access is allowed or denied, the prompt cannot be shown again. These settings can be changed by the user by visiting the browser’s/device settings for your particular website / PWA URL.
  • As an admin, you may work with multiple push enabled PWAs, so if you have allowed push for your earlier PWA then for new PWA you won’t show the push request access prompt again if you’re on the same domain. So for each new PWA you can clear cache of your chrome browser and re-enable the push notifications permissions.
  • If you are sending a push from the desktop chrome browser using the push sender editor module and you’ve subscribed for the notification then you must have open your PWA URL into other browser tab to receive it on your desktop chrome. This is because of you are currently on same domain at a time of push sending, while your other push subscribers doesn’t has to do anything, they will receive push notifications as usual.
