Has anyone encountered a "Map preview not available" message in a geopoint field when accessing a survey on a mobile device? I'm getting this message on an iPhone 6 and an iPad Air. Location services are enabled and I can still collect a GPS point, but I don't see a map. The same survey works ok on an iPhone 6 Plus. Just curious if anyone else has encountered this message and if anyone has any tips for resolving it. Thanks! PS - this is cool technology!
