Do people just not use the YouTube subscription feed?
I consistently hear people on YouTube complain that the subscribe button doesn't do anything for viewers, now that channel notifications are controlled by the bell. But it does do something: it puts the videos from that channel in your subscription feed, which is readily accessible on all versions of YouTube. So why do people act like it doesn't exist? I think it's super convenient, especially if you're subscribed to a ton of channels and don't want your notifications feed flooded with new videos.
Same problem, they really need good tools to allow you to quickly review your subscriptions - there's channels in there I don't care about anymore that spam out videos making my sub tab useless. They also need to allow you to migrate your subscriptions - my account predates when they were linked to your Gmail, so my Google play music transferred to YouTube music but isn't the YouTube account I watch videos on - it's a PIA I have to switch between accounts everyone I go from music to video or vice versa.
