I don’t think this is a surprise, they usually would air half the season and then go on hiatus. Season 7 was the only exception. It aired within two weeks in Italy and a span of 3 months in the US. They probably started production after the two seasons of World of Winx, and it may have taken longer due to the switch in animation.
