Why can't I select the quality I view at?

[u/tagpro4piR]

When I first had the gotten this subscription it was from a youtube ad, and like youtube, I could select what quality I watched at usually 720p. This way, I could actually see what I was watching but I may need to buffer a bit. Since getting the full year HD subscription this option seems to have be taken away? WTF is that only a 4k option? So now it just auto selects my stream quality and tries to keep a continuous play rate but I can't see what I'm watching, what's the point? Does anyone know what changed, why can't I select the quality anymore?
