Not receiving notifications on the smartband

My application is not receiving notifications on the smartband, although they work correctly on the phone. What might I be doing wrong?

do you mean notifications does not appear on your Smartband watch or something else.

You need to describe more clearly what is not happening and what extension you use to send the notification.

"Hello, I’m not using any extensions, only the notifier. In my smartband app, I select my application so that it displays the notifications. What could I be doing wrong? Do I need to use a different approach or tool? Thank you.
