3) After flight I uploaded the flight log to cloud storage and downloaded to PC running 3.0.5. The PC was unable to read the flight log created by 3.0.6 (is this a design feature?). If I send the flight log to my PC (running 3.0.5) by email and then import the GPX file onto the PC hen all is OK. Looking at the contents of the flight log it seems to be a binary file now instead of the previous text file format. The new flight log is happily read and displayed the Android device running 3.0.6 but not another device running 3.0.5. I have uploaded the flight log here to look at (after having appended ".txt" to the filename to allow upload with this forum software).
