Weirdly enough, both services didn't even officially announce this title. Only Aniplex of America did.
I was able to track down the time of simulcast and show pages, but at the time of this post both services didn't even promote it. Funimation is also very late on the business with their show page barely showing up and it seems to be suffering from the same issues that Fire Force had (page being region restricted when it shouldn't). In the meantime, Crunchyroll's is working.
