In Unity, I am making a small tool to upload our current local configurations in the editor to PlayFab using a SetTitleData request and it's working great until I hit Play and then stop the game. At this point, the requests never complete (neither result nor error) until, it seems, the assembly is reloaded since when I recompile it works once again, whatever the changes. It also always works while in Play mode.
Also, I don't know if it can be related, but when in Play mode the requests complete way faster than when they are done while not playing (if it works at all that is).
