> Instead, I have to explicitly go into "Subscriptions"

This is how I've always used YouTube, and it wasn't that long ago that I learned most people don't do it that way. My usual pattern is to go to the subscriptions tab and scroll down to where the last video I viewed was, then start watching from there up towards the top of the list.

It would be really handy if the YouTube app had some way of making that easier.
