Thanks for getting in touch and we appreciate the feedback. A fix is being rolled out to address non-admin's access to Files/Folders through Files API. If you are still in the development/exploration phase, you could consider following measures to unblock: 

a.      Temporarily add the user as the admin on the my site host web

b.      Temporarily get AllSites permissions for the app

I'll update this thread once the issue is patched in Production, which should happen very soon. 

Office 365 SharePoint v1.0 API Authorization Issue
For example, rather than running from places to places, I saw many fast travel icons on the map. Can I fast travel there?

I know I can fast travel to save sailing time. What about if I am not sailing? Why are they so many fast travel icons on one city? If fast travel is only when sailing, then we need only one fast travel icons per city right?

I am using PS4. In world map, I can fast travel with square key. What button I should press if I am within a city. I select a fast travel icon, press square, nothing happen.
