Our team member had offline data collection project using Collector for iOS on iPad. They wrapped up their project and we exported attachment photos. Strangely, some of the photos are missing geotag information. This is not user-specific or device-specific. Some layer has no problems, some layer has half of their attachments (80 out of 160) missing geotag information.
Has anyone else experienced this? Is this a known bug? Or user error?
Could the camera settings have the location tag turned off? This would not be a Collector setting.
