ZINO Pro + IMU Calibration Incorrect Images in APP ???

[me_b4749OpFaU]

I had a recent problem and installed an older version (2.7.0) of the X Hubsan2 App. During a test flight, it seemed a bit "drifty" and not rock solid like it normally is. While going through the calibrations I noticed that while doing the IMU Calibration that the images shown (#4) and (#5) seemed to be reversed.

Image 4 shows the drone on it's back,...... so after hours and hours and multiple attempts, the calibration would just stop there. By "dumb luck" I was looking over a few DJI notes I took for the IMU calibration and decided to switch positions of the drone for step 4 until "something happened" or the calibration went to the next step. It did go to the next step. I then saw that Image 5 shows the drone with the power button pointing down (Which is the exact position that I had it in on the previous step to get it to proceed). I then layed the drone on it's back for step 5 (like it showed in step 4) and it proceeded to step 6 and then finished calibration.

I did a search but don't see anything. Maybe it's just a glitch in this app version ? I don't remember having an issue before doing an IMU calibration.

Obviously if the calibration doesn't go to the next step, you have no idea what's going on so I wanted to post in case someone has the same issue.
