Hello Vinny,
As there might be many factors why you are having this issue, we need more information.
First of all, have you tried the steps below to troubleshoot Push Notification problem https://docs.appery.io/docs/testandde... ?
Also, could you specify the following:

iOS devices
Android devices
Both
Can you tell us how you send the Push Notification message:
Via Push Notifications dashboard
Via Server Code
Via REST API
Are you sending a message to all the users or it's a targeted Push Notification message?
If you are sending the message via the Push Notifications dashboard, can you send a test message and then go to Scheduled and History tab. For the message you sent - do you see an error message? If yes, what is the error message? Do you see any other errors there?
When was the last time Push Notifications message were delivered?
