Why isn't this feature already implemented by default in YouTube? It's 2023 !

I paid for the subscription just to shot videos on popularity to save me time, however in many instances it won't sort video on views, when I set it to popularity. The arrangement even with 100 or 200 videos filter it will show me old videos with high view but hide some. I have to go to channel page and individually check for videos which defeat the whole purpose of paying for subscription.


Update:
I appreciate your timely response and clarifying the details of the cause. It's alright I will just cancel my following subscription. but I would like to request a notification if in future you figure out a way to solve this issue I will gladly take the membership again. :)

Sort your Youtube subscriptions into categories or tags, yes please! Export and import your subscriptions across accounts, yes please X2.

Easily see all the new videos from your subs by category, amazing! After ublock Origin, this is the 2nd best extension.

This extension single handedly placed the giant Youtube into perspective. Thank you.

Sync data with Google Drive feature not working as it should be recently, it keep logout automatically without any sign so I have to keep redo the sync steps.

Update:
I reinstalled PocketTube addon yesterday like 20+ hours ago, import backup json file and enable Sync data with Google Drive again.
It works for now.
If the problem still happens, I will update information in this post.

Update:
Still happens but less frequent, it happens like 3~5 times a day now happens once a day. But still don't know why it happens.

Every this is good but the "mark as viewed" function annoyed me. It make me hard to click when i wanna save the vidieo. Hope dev can make a option to turn it off
