GPX data is incomplete for Street View export, exported gpx refused by Google

I made 360 video with Insta360 One X2 and mobile phone app. Then I wanted to export movie to Google Street View (by choosing Street View export in mobile app). But it always shows message saying gps data in file is incomplete and won't be accepted by Google Street View. GPS data is there though, because I am able to show stats for movie. Can you provide any tip what to do to make sure gps data will be complete for Google Street View export?

Second approach - I extracted gpx from movie file with exiftool. Then uploaded movie + gpx to StreetView Studio (https://streetviewstudio.maps.google.com/). But my movie has been refused with error message saying about time points don't match to movie.

Any tips?
