This we know. But I have the impression that Harman prioritizes Ilford (and Kentmere) products over all others they manufacture, so that when their production line is squeezed, all non-Harman products are sidelined until they have more time to produce for other brands.
Or perhaps there are raw materials used for Acros that have (yet again) become hard to source, creating an obstacle. There could be a number of reasons why Harman may have curtailed production of Acros II.
Regardless, I cannot invest in a film that has a track records of coming and going and may be rendered defunct at any moment, as Fuji is known for doing. TMX is almost as good in terms of reciprocity characteristics, and in other ways it's superior. It is certainly far less expensive: $8.00 per roll, versus $12 (or more) per roll for Acros II.
