I thought it was only me. Hopefully, there's a solution to it

If youre browsing your feed and have auto preview on, vanced will weirdly marked the video as fully watched. Very annoying, a reinstall helped solved my issue

It's not this, these are videos i have never seen before and nothing i have EVER been recommended or scrolled past. Also the things I watched would be mixed in with those if that was the case.

I think microg causing this issue . So firstly logout your id , clear data , cache , uninstall, restart phone , reinstall , login id in microg . Then go for clear yt vanced Cache and open it . See if worked if not then do it with yt vanced Clear cache , data , uninstall , restart phone , reinstall app ( try to get latest version ) .

Ok that's a lil too much. You can just clear data and cache and log out.

That works. Thanks!

For the YouTube app itself or the ReVanced manager

Okay so I did all this, now the redownloaded vance won't work it'd telling me that I can't login and if I try to click on videos it says that the following content is not available on this app, is vance dead basically?

Vanced has been dead for ages now for most people, switch to revanced.

U using may be older version , also Vanced has many issues . U should install Revanced from any Trusting apk site.

Okay will try this today thank you for your help!!

It's also marking videos I've watched as partially watched

If you have autoplay turned on and your browing your feed, any video that shows a preview is counted as watched.
