How to restore notifications from YouTube?

Question

YouTube

Hello. Like many others, I am subscribed to many YouTube channels and receive email notifications on GMail. And now, for six months now, I simply have not received these same notifications. YouTube settings are as they were, GMail YouTube did not ban, but there are no notifications.
Is there any service that will give you a custom YouTube notification feed?
Let me explain. Often there are different branches-plots-headings on the channel, not all of them are interesting to me. For example, if there are recipes on the channel, I don't need them. The YouTube mailing list sends out everything from the channel, but I would like a more precise setting.
I would be glad to help, because I have already missed a bunch of new videos and I will continue to miss. Going around all the channels yourself is very tiring.

Go to each channel, and click on the bell, this will turn on notifications.
