@YouTube, I keep getting an error message whenever I try to add videos to my Watch Later list, am I the only one this is happening to or are there other people? I'm using the app and I'm on Android btw
That doesn't seem right. Try uninstalling the app updates, restarting your device and reinstalling them? Here's how: Open the Settings app > Tap Apps > Tap the YouTube app > Tap ⋮ > Tap Uninstall Updates. Also, mind sharing a screenshot of the issue? Let us know.
