Today I got an update dated 21st Aug with the same Android version 4.1.5??? Didn't noticed though the build #. Only changes are for spark and some bug fixes (even for spark but what has been fixed?). Proceed to update and I noticed some prompts are too less opaque, some editor screen menus are overlapping which I don't care but worst of all I lost all my cached maps including maps downloaded for my coming EU trip duh! Luckily it wasn't set to auto update...

Re-downloading...
Also requesting for DJI devs to please allow maps to be cached in the sdcard, like the live feed. Almost all GPS apps I use allows this.

I updated today morning. I will check it out.
Cheers.

Thanks for the feedback. What mobile device are you using? Could you please provide us the screenshot with the overlapping of the editor's menu? I'll help to reflect.
