Insta360 One App - Speed Settings

Hello.

I recently purchase a Insta 360 One.

I have been dealing with the iPhone App and my doubt came on the Speed settings.

All videos i watched online (mainly on the One X) show that i can edit different speed settings troughout the video.

But when i use the Insta360 One App and click Edit --> Speed - It shows a message saying that speed setting will only be applied on export.

And it wont let me choose different speeds for different parts of the video.

Is that a limitation on the Insta 360 One?

Or am i doing something wrong?

Thanks for all,

Giuliano
