Why is Youtube not working on my iPhone? How can I fix this?
Okay, I tried that but it's still not working. Do you have any other suggestions?
Another thing to try would be to check to see if the app needs to be updated. You can do that by going to the App Store and checking for updates. If there is an update available for YouTube, try downloading it and see if that resolves the issue.
