Seafrogs Sony A7 IV Housing

Seafrogs has released their housing for Sony A7 IV, it is the same housing as for the rest of their Sony A series line up but doesn't include the function for Mode Selector or Joy stick.

I don't have an A7 IV yet and I have been waiting on the Seafrogs housing, does it mean that if the mode selector is set to photo that we can't record video and vice-versa?

There is a record button on the Sony case, but there are some drawbacks if you start video recording in Photomode. 
At this point this not direct experience from myself but in this case some AF options are avaible, so if video is something you want to use all functions, you should get a case where you can switch to video or even high speed video. 

If the record button doesn't give you all the necessary AF functions in Photo mode then this housing is rubbish for people who would want to take advantage of the improved AF system in A7 IV, I might as well stick with my A7 III.

According to this review he mentions if you are in Photo Mode and you press the record button, your auto focus gets stuck and you won't be able to use auto focus but he says it could be due the lens that he was using. It would be nice to get this confirmed by other A7 IV users.
