Does anyone know why the manga was canceled?

There's suprisingly very little info regarding the manga's cancellation. The only news source that says it was getting canceled was Anime News Network (every other news source referenced the ANN source and I found zero Japanese news sources that talk about this cancellation).

But now that this has been confirmed true, I'd like to know why it as canceled. The best I could find about the manga ending is this one random Japanese tweet, that Google translator says it means:

#Kimi Battle In the second term, the scale is not enough and comicalize can catch up quickly, so the serialization has expired. It doesn't look like the illustration, but this one is more like the original.

Can anyone confirm that this is true? That it was canceled because the light novels aren't coming out fast enough to keep up with the serialization? And if this is not the reason, then what was it?
