The Collector app (10.4.0.0) on Windows 10 does not attach photos from the camera. While I can take a photo from the camera window, the 'tick' button remains greyed out and the 'waiting' window just hangs.
I've now tried the Collector app on four different Surface Pro 4 devices & all experience the same bug.
I can attach photos and documents via the 'folder' button.
Please let me know if this is a known bug & when it will be fixed.
