@albert-garrido-casòliva Please open then .mp4 file while you have the .insv file in the same folder have both have the same name.
Street Builder will read the frames from the .mp3 and the GPS from the .insv
Your tour was fully map rejected, for cases like this you need to delete the tour from Google and then publish it back. Just updating does not do anything beside updating metadata for a map rejected pano. (that does not make a pano map approved)
@stéphane-de-greef The moderator supports only Google Maps, we are using Map Box in the Tools section so we mitigate the usage cost Google Maps API has.
I understand your point. The thing is right now our focus is not on the Moderator but on the Overlay Editor, and we have no idea when we will go back on the Moderator. But when that will happen allowing you to switching between OSM and Google will be an option.
