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 autor Hiro Mashima might be getting busy o that he changed the día again.

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