Insv file to mp4 problem

Hi!
I have a little beginner problem, that i wish someone could help. Im not sure which category suits best on this question, so i decided this Tutorials category.

So the problem is this, i just bought Insta 360 oneR, and i recorded some test videos. They really looks really good when i watch them on my mobile phone, or on Insta 360 studio. I can move freely the scenes 360 degrees like it should be.
Then i tried to export those files (insv-files) to mp4-files on Insta 360 studio using export button.
When export is finished the mp4 file is not anymore 360 degrees, i tried watch it Insta 360 studio, and some other media players. But looks that changing insv file to mp4 file, somehow the video does not support anymore 360 scenes.
So i need help, im doing something wrong on export, or what i should do that exported mp4 file is still on 360 degrees?

I need mp4 file, so i can edit and make little film and placing there some music using 360-footage on my Insta 360 one R. I have Sony movie platinium (i think this software doesent support 360 footage) and i have also Hitfilm express, if i have unserdtand correctly Hitfilm should support 360 files also.
If you have some software that you could recommend editing 360 footage, adding music and making little films i would happily hear your recommendations. :)
