We'd like to help. Have you tried uninstalling the app, restarting the device and reinstalling the app to check if that resolves the issue? Also, does this happen across devices? Let us know.
Appreciate the info. Please send a feedback report directly from YouTube with these steps: https://goo.gl/WdI0BK . While every individual report may not get a direct response, we do review everything and use the details to investigate and fix issues. Thanks!
