Seriously, what the fuck? I thought it was some kind of user interface glitch so I looked it up. Nope, they're A/B testing this shit.
Found this brilliant statement by Youtube on the matter:
Now note that we are deprecating one sorting option and that is by oldest video at the channel level. But don’t panic, you can still view the oldest video of a channel, by scrolling through it’s content’
Oh, yeah, just scroll to the bottom. Silly me, I guess I'm just a stupid idiot for not realizing the option was redundant since I can simply take the time to scroll through potentially thousands of videos.
Why are silicon valley tech people such freaks?
I'll still never forgive Amazon for when they did something similar to their wishlist system a few years back.
I had a bunch of big in-depth lists that helped me keep track of all sorts of different stuff, all of which were basically rendered useless after they severely limited the sorting options (Most notably removing the abilities to sort alphabetically and by date added for example) for literally no reason.
In a nutshell: :lord-bezos-amused: :stalin-gun-1:
This is why I just stick to bookmarks or written lists. I stopped caring about favoriting videos in YouTube about a decade ago because the list ended up being half [removed video] due to DMCA claims.
If nothing else I wish they would keep the title of the video up or something so you'd at least know what it was later, instead of possibly forgetting it forever.
also when sorting A-Z, you have no idea if the the first letter is going to be the product name or the brand's name, and it'll always be inconsistent.
