I have a field user in a remote island in the Pacific.  He downloaded an offline version of the map before departing the US.  Got an email today with the below screenshot.  

Any help is greatly appreciated.

I also have users reporting this error on iOS devices.

I'm having this same issue for the first time. I have never experienced this before today. Any movement or suggestions on a solution for this?
