Youtube notifications disappearing. Android 14.

[Advaitom]

I'm using Android 14 on a Samsung A73 with OneUI 6.1. I'm subscribed to a bunch of Youtube channels. When I turn on my phone's data connection in the morning, I get about 10 to 15 notifications from my various Youtube channels. But about about half or more of those notifications disappear and I only see them in my notification history screen. Why are most of my morning Youtube notifications disappearing? How can I fix this? I googled this issue and could not find a solution. I turn off my Youtube app before going to sleep. Do I need to turn it on before turning on the data connection?
