As AnimeNewsNetwork said in their news:
On the 27th of next month, July, Kannagi will restart serialization. As the article says, three chapters will be released month by month, and then, due to the conditions of the author, it will slow down to a chapter every two or three months.
Also, since it’s been licensed by Bandai, we will have to block visualization and download from USA, in order not to damage the publishers.
Personally, I can’t wait to work again on my favorite manga. We will deliver as soon as possible.
