Anyway, during the clash with Fuu, it didn't seem that the latter tried to use Shintenshin and failed, rather that Fuu only made the hand sign, but didn't have enough time to initiate the technique.

Regarding Kamui, well, if his mind can perceive both the real and Kamui dimension evenly, it means that mind-affecting techniques should still be effective on him even in intangible state. At the same time, Izanami needs some physical requirements (the setting of "A" "B" "C" events to create a basis for a loop), while it would be hard to met this conditions if Obito doesn't have a physical body.
