Found more information why Nick UK is not airing rest of Season 6 Episodes

Feel like Nick UK & Ireland are getting 611-626.

Note: From another blog here titled Winx club season 6 episode 17 coming out information is unofficial & confirmed, I will be looking further information regarding about this off of Nick USA site.
