@TeamYouTube Some weird reason, when I like a video on mobile (recently possibly the last two days), it would say added to like videos, but it would unlike once I leave the video I tried to see if it would undo videos I recently added to the playlist but it didnt. Please fix.
To help the right team better investigate, can you send a feedback report from the device having the issue? Steps here: https://goo.gl/WdI0BK . You may not receive an individual response back, but the details will help us identify and fix any issues, thanks.
