How long until a transfer becomes official?

So despite my best campaigning against it, Riot is content with letting EUNE die with the removal of Normal Draft (as well as making it a Polish server - why are the news and stuff in Polish by default, Riot?! WHY?!) I've jumped to EUW instead. But as you can see, it still says EUNE on my profile and I can't do things like use the EUW store yet (apparently it forgot that I verified my email as part of the transfer?!).

So... how long does it usually take before the game/client/servers gets the memo that I switched servers...?
