I no longer have faith that Ricoh will ever address this issue.
I have been using a 3rd party tool called Geosetter, which you first export the GPX from your mobile (yes the same one running the theta app) and then use this to attach the more detailed location to your images.
This avoids the Theta apps’ low resolution GPS coordinates, which it rounds to 4DP in the Exif.
Then you transfer the thousands of images back onto your mobile and upload to streetview or other location.
I am not happy that Ricoh still hasnt addressed this and I had to develop this insane workaround.
