Do not receive comment notifications for my Facebook page

I run a Facebook page and when someone posts a comment, I should receive a notification.

It worked well. I received notifications whenever someone commented on my information. Suddenly, it stopped working and I can not fix it.

I noticed it about 2 months ago. Could it be that he stopped sending notifications because I write less than what I wrote for about 3 months?

I guess it is a recurring problem because I have found other people who were asking this question.

Here are the notification settings of my page
