When a notification shows as "Delivered" in OneSignal, it means we have successfully sent the notification to the FCM (Google) / APNs (Apple) / WNS (Microsoft) servers which then distribute the notifications to your subscribers. The following are reasons why notifications may show as "Delivered", but are not visible on your device.
This is the most common reason. Check your browser settings as follows:
Check Settings > Notifications & Actions > Turn on Get notifications from apps and other senders. Make sure your site and browser are also enabled. More details in this article: https://support.microsoft.com/en-us/windows/change-notification-and-action-settings-in-windows-10-8942c744-6198-fe56-4639-34320cf9444e
In System Preferences > Notifications > your browser of choice, make sure notifications are toggled on and set to Banners or Alerts.
If subscribed to a website on Safari, you will also see options for that site. Make sure notifications are also turned on.
In System Preferences > Focus, check that you currently don't have a "Focus", "Do Not Disturb" and/or "Sleep" enabled., make sure this is mode is not turned on or you are within the time notifications are allowed.
Check in your Settings > Notifications > Chrome (or browser of choice). Make sure "Show notifications" and your website are checked.
Devices must be online to receive push notifications. If your device is turned off, in airplane mode, has unstable or no internet connection, the push will not show until a proper connection is made. You can set the timeframe Google and Apple Servers will wait for a connection with the Time To Live (TTL) Parameter (the default is 3 days).
Also check the network / WiFi you're connected as it may have closed your connection to Apple or Google servers'. Try disabling and re-enabling your internet connection. See our Notifications delayed troubleshooting guide for more details details.
Make sure your device is still subscribed to push notifications. You can find your player id with this guide to make sure your device is still subscribed.
Check the segment you sent the push to and make sure it is setup correctly. This is under Segments. Sometimes an incorrect filter is added to the segment removing certain devices.
Check your site's codebase for the
.unregister() method. Calling this method will delete Service Workers. See this guide for details on this method.
If you have another service worker like for your PWA you will need to follow our Service Worker guide on integrating multiple service workers.
Browsers will not receive push if it is not running. Make sure to open the browser.
Clearing your browser cookies, data, and/or history will cause the browser to not get notifications any longer and will need to revisit the site to re-subscribe. See Clearing Cache and Resetting Push Permissions.
If your mobile browser app has reached its data limit or its data is full, you will need to clear the data on the app.
If your mobile browser app has many unread push notifications and/or many tabs open, this can cause notifications to now show.
Users must subscribe to notifications on their desktop or mobile device to receive notifications and it must be a browser that supports push notifications. Please see Web Push FAQ for Supported Web Platforms.
