Yup. Eliminate the cheaper, better competition, under the guise of xenophobia, so you can have a monopoly of far more expensive, less capable, patriotic offerings!
As far as I can see the latest firmware available for a Mavic Pro is still v01.04.0500 from 2018/09/03.
Maybe you're talking of a separate flysafe update? That's not firmware so be clear if that's what you mean.
Especially since the OP is coming from an iPhone as a video display.
No change at all in the operating system and app when switching to an iPad instead.
