For the past couple of weeks, I have been unable to sync my flight records with DJI Go 4.   I am flying an Inspire 2 and all has been working great until around the first of this month.  However since then, I've not been able to sync and get a sync failure at 58%.  
Any thoughts?

Hey Mark, I was having trouble also. Today I opened the go app and was prompted to "log in" , after logging in I went to my records hit the cloud and enjoyed a successful flight log upload. So log out then sign back in and it should work. Safety First! Ken.
