I voiced my disappointment in a similar thread last month. Having updated the app to 2.56.0 it did help somewhat and at some point the app has since automatically updated to 2.57.0
Where I am now is that the focus is still off, but not by much. Can I live with it? Probably not. To date I've been taking off with my Mavic in DJI Go (also Android), elevating to the desired altitude, adjusted manual settings before pulling the USB cable, wiping the defaults and restarting in DD to initiate the mission. The Android work around I can probably live with, but I wish the focus could be mended.
Unfortunately, my trial has now expired and whereas I was evaluating on behalf of my company, I am no longer able to carry out the various functions required to prove its worth. I have received a quote from a DD Reseller and before taking the order they suggested I continued with another trial period first. I do have an email out to Eric to reactivate my account and await a response.
