I genuinely don’t understand why @YouTube thinks it’s ok to not notify subscribers when the YouTube channel they SUBSCRIBED TOO uploads. When you SUBSCRIBE you ask to be NOTIFIED. This is common sense. When you subscribe to a subscription box or magazine, you’re choosing this!
The default setting is to receive "occasional" notifications, which is the "algorithmic" or "affinity" part. But if you tap the bell for a specific channel and choose *all notifications* then you receive all notifications for every upload.
