I am using an iPhone 6 with the OTG. All firmware up to date including most recent Autopilot (4.2.156).@srcrain and

That's very strange. What kind of mobile do you use?
Today I did a waypoint flight with 8 WPs, also used focus triggers at each WP. Spark flew to all of the points, camera angle as desired. No jitter or other strange behavior.
After that, I tried a pano. Spark flew to the programmed height and all photos were taken.
I use an iPhone 7 with latest Autopilot (4.2 156) and latest DJI Go 4.
Autopilot does recognize the Spark, as it says Spark connected. The jittery/stuttering flight has stopped though since the latest firmware, which didn't really mention anything related to Spark,, so that is weird.
