1. Thankfully, core functionality is still present.
2. At the same time, watched/unwatched function doesn't work as intended anymore. It's equally as important to me, I'm waiting for it to be fixed for more than a week so far and start to dread the possibility of it never working properly again.
How it worked before: you saw only videos you didn't watch yet on any given page. Pockettube was automatically scrolling and organizing it.
How it works now: any given page loads up with both watched and unwatched vids. Next step, I uncheck and check again the "watched" button, which simply hides the watched videos previews but doesn't re-organize or scroll the page at all. If I manually scroll one screen down, there are watched and unwatched videos mixed together. As in, this feature doesn't work anymore.
Please fix it asap! I already looked for alternative apps with watched/unwatched functionality but Poskettube's was better than any of those other ones.

Update: yes! It is working properly now! This developer responds quickly and fixes bugs (if you care to report them) even quicker. Sad that YT update broke some functionality, but oh well, can't have everything.
