Hi,
You can refer to the link below to troubleshoot if you can't see the push notifications on your phone.
Why can't I receive notifications after turning on Notifications?
 

If the problem remains, please help confirm the following information.

1. On the Tapo app>Home page, tap the Message icon at the top right corner, and can you see the notifications on this page?

2. What's the model number and OS version of your phone? If you test with a different phone, will it receive the push notification properly?

Best Regards
