This person has created a thread about the same thing.
Being honest I've not come across this as I personally do not use many of the features within the camera but fully appreciate some do.
I'd suggest to use your Samsung Members App / Samsung + App to send this as feedback.

I have been reporting on the Samsung members app for over a month now that the ability to record video in pro mode is no longer available although it still says 'take control of your videos'.
I've never been given an answer to why this this.
An embarrassing oversight from the software developers.
im going to give like for all the post about this topic, to push up the tread that Samsung should take notice. They can't just simply remove this feature, and before this, the video recording pro mode can be turn on via Voice command "Record video" yet they patched it, wondering why they disabled this on purpose?
