Hi All,
Long-time Inspire 1 user in Dubai and just got my Mavic after waiting for 2 months. First flight, calibration done, 12 GPS sats acquired, firmware updated (1.0.3) and took off. Immediately after it was hovering a few meters above the ground and started drifting immediately. I have checked multiple times for any issues in the settings but just can't seem to fix it and am now using all defaults yet still get the same issue. I did read elsewhere on this forum of this issue but I thought it was fixed in the latest firmware?

Could you please sync your flight records from DJI GO app and provide me with your DJI account email? I'll help to check it.
Is your DJI account email the same as your forum email?Besides, please upload the flight data to dropbox and send me the link.
You can use the same method as for the Phantom 4.
Here is a video tutorial for reference:
