Cannot Export Files from IQANgo on Android

A customer notified me of an issue with IQANgo on Android - when attempting to export a log file from the app an error window appears as shown in the attached image. I managed to reproduce the issue myself on another Android phone. Both phones have the latest Android version, as far as I know this has just started with the the latest IQANgo app version 7.02. May you please investigate?
