If you know of a way please let me know and I will add instructions on doing so to the article. I could not find an option in the app to sign out other than the aforementioned lag bug when switching between normal and incognito mode. There does not appear to be an option to sign out of the YouTube application once you are signed in and Incognito Mode becomes available on the device. The option to turn Incognito Mode on or off replaces the sign out option in the YouTube app. Using Google without sign in limits the functionality on the site somewhat: you can't use subscriptions, messaging, or use other functionality on the site when you are not logged in to an account. Incognito Mode offers similar functionality to not signing in to YouTube in first place. Select Paid Memberships from the menu, tap on the menu again and there you have the sign out option. Update: Apparently, there is still a way but it is quite hidden. You can exit the mode at any time by tapping on the incognito icon that is displayed instead of the profile icon and selecting 'turn off incognito'. Incognito Mode is turned off automatically after a period of inactivity. When you open search, YouTube reminds you that the search history is paused while the mode is active. Tap Menu (located in the lower left) then tap Remove account. These instructions apply to Standard mode only. From a Home screen, tap Apps (located in the lower right). Other parts of the app may remind you that activity is not recorded. Removing then re-adding your Gmail account often fixes login and not receiving email issue.

Some functions on YouTube, subscriptions, for instance, become unavailable while you are in incognito mode.
