Description

Seeing login warnings repeatedly when downloading from YouTube. Used to work without this error a few weeks ago, updated to the latest version and it is causing these warnings. I have logged out in a browser on the same machine and logged back in successfully using the same credentials. I have updated the cookies.txt after successful manual login as well.

It does seem to download the videos properly.
