@YouTube @TeamYouTube I don’t know if this is just me or if it’s happening to multiple people but for some reason I can’t reply to comments on vids. If it’s happening to more people you should get it resolved after the holidays.

Thanks for letting us know. We'd like to confirm if this is a device/user specific issue. Could you check if this happens across devices? Also, try signing out and signing back into your account to see if that helps. Keep us posted.
