I just got a brand new MA and during the initial set up I noticed an ACC1 Data Error message when calibrating the IMU. Re-calibrated several times, downloaded the Assistant 2 pack for my MAC, reset to factory, un-installed and re-installed the Go4 app from my phone, and the issue did not resolve itself. Now, I'm worried because, according the company website DJI's support is closed for the weekend and it's Friday night and I only have 48 hours to purchase the Care Refresh which I don't want to do with a defective drone. Sigh. Any tips?
