Yeah it is pretty odd that Sentai make no mention of streaming for the first two. For Season 1 I guess it's understandable considering it's on Crunchyroll but then again series like Cinderella Nine and Between the Sky and Sea started on CR before being licensed by Sentai and later showing up on Hidive. Same can be said for Amazon series like Magical Girl Site and After the Rain.The series has had an awkward licensing history. Season 1 is on Crunchyroll. Season 2 was on Amazon Prime, but was removed earlier this year, and season 3 is exclusive to HiDive. While Sentai have licensed all three seasons, their press release was ambiguous on which rights they've acquired for the first two. I asked them about this on Facebook, but didn't receive a response. The first episode of season 3 is on HiDive now, but there's no sign of the first two seasons. It's possible that they might be for physical release only.
That said, having watched the start of season 3 (which was a great opening episode), I don't think it would be too jarring to jump from season 1 to 3, since half of season 2 was a prequel anyway.
In short, licensing is never simple and makes no sense
