I see that DJI released a new firmware for the A3, version 1.7.5.0. From the release notes:

I can't install the 1.7.6.0 version using DJI Assistant 2 for autopilot V 2.0.0.

Can anyone tell me why?

I too cannot update theA3 to version 1.7.6.0
I updated the Assistant 2 to the  2.0 version
I can refresh the current version 1.7.5.0 successfully
When I select firmware update and click on upgrade, I get the following - UPDATE FAILED
I noticed the following on the page prior to the update selection.  "Installation  coordinate value has been reset. Confirm?

Any ideas???????
