@TeamYouTube After changing my google account picture and name ALL of the channels I’ve subscribed to have gone and so have the videos I’ve liked and added to my watch later playlist have gone?? Why has it all disappeared ???????
To clarify, changing your Google profile identity (Picture & Name) will not effect any of your YouTube's data. You'll still be able to see your playlist, liked videos & channel's that you've subscribed to. Could you confirm, if you've signed into the right account? (1/2)
