The refresh during the process like unification, activities upload, relationship, etc takes a lot of time due to backend work which is quite understandable.

but if the team can update the approximate time it will take to get the work done will help the customer to plan the other part of their work accordingly as we need to sit idle till the time the refresh is happen or are not able to concentrate at other work as we don't know how much longer it will take for the refresh.
