Link to certificate fails-No push notification seen

I’m trying to activate the extra features. I uploaded my signed certificate, and I see the Link to Certificate button under my iPhone device. I click it, and I see a green notification on the bottom “Notification sent to the device.” But I don’t see the notification, so there’s nothing to accept. I’m stuck. I’ve tried initiating the process from my iPhone XS as well as from my laptop.

Please help me figure out how to find and accept the push notification.
