Why are my push notifications being sent with a significant delay?

If you notice a significant delay in the delivery of your push notifications, especially when sending to a large audience, it may be due to a sending rate limit configured for your application.

A sending rate limit (also known as throttling) controls the maximum number of push notifications that can be sent per second for your entire application. If this limit is set too low for the size of your campaign, a queue will form, and messages will be sent at the throttled speed, causing delays.

This is a global limit for the application, meaning it affects all campaigns running simultaneously. For example, if a large campaign is being throttled, even small test campaigns sent at the same time will also be delayed.

To resolve this, you can adjust the sending speed limit:

1. Navigate to the settings for your specific application within the control panel.
2. Locate the Throttling or Rate Limit settings section.
3. You can either increase the Sending speed limit to a higher value that accommodates your campaign volume or remove the limit entirely.

Adjusting this setting will allow your campaigns to be sent out more quickly and prevent future delivery delays.
