GMail stops sending push notification to WEB - push-notification

I've configured the push notifications following this guide and when calling the watch endpoint I get an expiration of about one week.
During this period I expect to receive notification to the Pub/Sub topic I've configured without the need to call the watch endpoint some time before the expiration date.
However what happens is that after about one day I'm not receiving notifications anymore and calling the watch endpoint doesn't help.
Why GMail has stopped to send notification to the subscription endpoint?

FCM web push message received in DevTools, but event not dispatched

I've been working in bulk web push notifications, migrating from OneSignal to Firebase. I've created a single FCM topic to which all users are subscribed immediately on startup.
At first messages arrive on the browser and the notification is shown correctly, but randomly after a few hours and in some devices, notifications cease to show. I've been recording every push message received using DevTools, and noticed that the messages are being received but the push event not dispatched in those cases.
In which cases something like this may happen? It's worth noting that the service worker has been healthly with no errors whatsoever.
Thanks

How to Test FCM Data Push Notifications Delivery?

I have an Azure Web Service which is using an Azure Notification Hub to push data notifications using FCM via Firebase to a Xamarin Android App. Initially the app is getting a token which is posted to the web service. The web service then sends it with the data to the notification hub which is sending it to Firebase. The response back from the hub is indicating a successful transfer it seems from the notification properties and the ReqID property. But the notification is not reaching the app. Is there a way to see individual notifications' status on the Firebase site? Currently I don't see anything under the "Cloud" report for Data.

Thanks for asking question! One of the notification failure point could be when sending it from FCM to user device. To confirm this, you may try getting a delivery receipt from FCM.
You may refer to this article Receive delivery receipts. It says for Android and Chrome client apps, you can get delivery receipts which can be sent from FCM to your app server. To enable this feature, the message your app server sends to FCM must include the field delivery_receipt_requested. When this field is set to true, FCM sends a delivery receipt when a device confirms that it received a particular message. Also check for firewall on the user's network.

FCM send message to topic with local time zone

I'm using Firebase Cloud Messaging for IOS and Android.
I want to send message to topic in certain time
considering local time zone. Is it real by using API?
I know that it's real by using custom scheduler and storing user time zone, but I'm looking for easy way.
You can schedule messages in the notifications composer panel in the Firebase console, and you can select for them to be delivered in the user's timezone there.
But there is no option in the Firebase Cloud Messaging API to schedule the delivery of messages. Messages sent through the API are delivered as soon as possible after you send them. See FCM Schedule delivery date or time of push notification.

How can i push message while client not visit my site?

I use serviceWorker to push client desktop notification. Clients receive message if they visit my site, how can Clients not visit can still receive the message(like onesignal.com)?
Clients/Users don't have to be on your site to receive notification.
But your client/user has to accept the notification request in your site at first, so you save the subscription object in your database and later you use that user subscription data to send notification to your client/user at any time using library like Web Push API.
If you need anything in particular, please be specific.

multiple endpoints with same token in AWS SNS

I am using AWS SNS for sending push notifications and I have used this article for the implementation http://mobile.awsblog.com/post/Tx223MJB0XKV9RU/Mobile-token-management-with-Amazon-SNS
I am storing the token and the endpoints in the server for sending the push notifications, but the problem is with GCM when the reg_id gets changed and pervious reg_id is still active then the aws update the pervious endpoint with latest token, due to which I have got two endpoints with same reg_id and when I am sending the push notification then it is getting delivered twice.
I have searched everywhere but I am not able to find the solution, how do I update my server DB to delete the older endpoint.
