Yokohama	Yokohama Patch 11 Changes to Now Assist usage measurement Starting with Yokohama Patch 5, Now Assist usage measurement is transitioning from a 365-day look-back model to a 365-day burn-down model, with usage resetting at the contract anniversary date. For more information, refer to KB KB2704710: Now Assist Usage - Overview & New Measurement Logic. Some Now Assist skills are turned on by default The new default behavior works as follows: New customers: When you install a Now Assist product, designated skills are turned on automatically.
