No its not. I use it as a daily workflow. Every notification I get, I open the video and add them to my watch later using keyboard and mouse when I have a spare moment during work.
Now I have to do that on my phone which means that if I don't want to do it, the notifications pile up and I lose track. So currently, I say: screw it, and I just swipe away those notifications, which means that I'm also swiping away LTT videos hoping that I don't forget to add them later which I'm seeming to forget. So yes, it pains me to say it, but I'm not watching as much LTT videos because of this.
Youtube really is dying to me.
Also, I am a content creator myself, although I don't have enough subscribers to be counted as a content creator to youtube, so no premium support, but since about 4 weeks, I see that my videos are not watched that much anymore. Its hurting me in so many ways.
