"Due to the new API implementation, the moment you refresh, you will immediately receive a D rank regardless if you have finished the battle or not"

It doesn't necessarily give you a D. When I refreshed, not knowing they changed it, I ended up with a B. I think the rank depends on how your ships are doing by the end of the day battle.
