Does anyone know why Fairy Tail is coming out less?

I honestly don't know either I think he changed it from coming out every Friday to Monday and then he changed it again. The author Hiro Mashima might be getting busy or that he changed the day again.

Edit: Forgot to mention that Fairy Tail isn't liscenced on most sites anymore so you either have to buy it or find a site that still has it. Hope this helped you ;)
