Updating episodes and the TVDB

I don’t know how this all works but I just added an episode to TVDB but when I refresh ND it does not update.

How long does it take to show the change and is this delay on ND side or TVDB?

It has to go through trakt. Info gets added to TVDB, trakt gets that info (nightly/manual if you’re a premium user I believe), then NzbDrone pulls it in every 12 hours (and also does some other backend updates at the same time).

Cool, thanks.
