@YouTube your mobile app has an issue where it mistakes me touching the bottom menu for me clicking a video or story next to the menu. 9/10 i am absolutely touching the menu and it still drags a video on screen.
That's odd. If you're using an Android, uninstall the app updates > restart the device > update the app. Also, if you're using an iOS, uninstall the app > restart the device > reinstall the app and try again. Let us know if this helps.
