To clarify, all works as expected with the local cache/manifest server if MAU is up to 4.15 and all MS apps are closed. If any MS apps are open with unsaved files then it stalls, never notifies to quit apps. If you go ahead and quit any of the open MS apps then it will continue. Also, here is a fresh log, just dealing with the scenario I just described.
