In our Microsoft Ticket with TrackingID#2201260040005531, it was recommended we open the idea. When the pool's bookable resources hours have been changed, we request the Pool's work hours be automatically update. The MS rep said this feature is working as designed and the pool hours are not being updated today.

We have used this additional step to recalculate the hours. We have recommended to our customer to change the Bookable Resource Pool Derived Capacity to No and save the record. Then change the Derived Capacity to Yes and save the record. Refresh the Pool Bookable resource record to verify work hours have been modified.
