No, there's no proof anywhere it was axed or cancelled. It's just slow uploading is all. Some manga update weekly, some update monthly, and some even update every other month. It depends on where they were published and who the editors are. Japanese publishing works significantly differently than how other countries do things.
Another thing I noticed about people hating this manga is they are veteran readers. But I think this manga is geared towards newer readers. Follow me on this. A lot of books out there are designed for adults, young readers, kids, etc. right? I think manga is the same. Never mind the genre or demographic but I think manga are geared for levels of readers as well. This manga is meant for people starting to get into that area: Easy to Intermediate if you will. But most manga veterans are somewhere at Advanced or beyond so naturally manga like this will be aggravating. These readers want something complex, different expectations, in-depth descriptions and scenes, etc. But those not as experienced don't care yet.
Anyway, that's just my observation. Take it for what it's worth, if anything at all.
