For me it's an other behavior, it was working at my first attempt with the new update, then leave game, edit my own snapview/view, launch game...not working anymore, but fine with others aircrafts (Su25T, KA50....). I disabled all my mods, made a repair, and after TIR was working again with the M-2000C, strange.... i've tried to save an other snapview while in game, just for testing, with the Mirage, TIR don't work anymore once you set up a new view, the only solution is to made a repair to re-enable it.
