VESC Tool (Android) and save “App Cfg” (save failed)

I'm not sure if this has been mentioned here before.

It looks like there's a bug in the Android Vesc Tool version 6.02.

When I try to save the “App Cfg” data on my Android phone, I keep getting an “Appconf Save Failed” error. However, a 0 byte file is created with the given name.
When I do the same for the "Motor Cfg", everything works fine!

This problem has been replicated by other Android users.

Does anyone here know a fix for this? (Buying an iPhone is not an option!)
