DJI Waypoint mission does point at POIs
I have create a simple DJI Onboard Waypoints mission, execute ok in preview, actual mission does not point at the POIs. See link to Airdata record of the mission.

What am I doing wrong. Link to mission

Should read "does not"
The drone is a Mavic 1 Pro Platinum, mission flys ok in AutoPilot using "continue on RC lost mode".
There appears to be some conflict with the POI and how you have planned it directly as DJI waypoints. When we created this feature originally, it wasn't really intended that users would use DJI waypoints directly, but rather by converting existing waypoint missions. For example, I took a stab at planning a similar mission as waypoints: https://app.dronelink.com/dronelink/support/plan/FDNe5pDyX7BupEHE1eN8/4eYf7kcaQZwOV8Rgkx7N
If you convert this and fly it, does it work better for you? Please check it first for altitudes and stuff as this was just a quick pass.
I also have a normal mission, like the one you created. The Converted missions untouched work ok. The original and converted missions are far too slow from the programmed maximum speed. To increase speed on the converted mission I increased the radius at the waypoints and add POI to the waypoints to reduce wandering from the POI, the speed was good but the POIs were ignored as you see in the Airdata. Thanks for your response.
I created a new Waypoint mission "converted" the mission to onboard DJI Waypoints with a waypoint separation of around 100m, I set the waypoint radius to 150m and speed to 50km on all but the first and last waypoint. The mission flew perfectly always focused on the correct waypoint, except for a brief period when leaving the first waypoint, it slowly yawed to the set POI, good speed 50k/h in straight sections a lowest speed during orbit around 43k/h. It would be good to add two addition options to the convert dialog, in addition to waypoint separation, speed and curvature. It looks like setting POIs on Waypoints on the converted mission is messing up the mission.
My experience with the normal app controlled Dronelink mission is it will terminate once the speed gets above 30k/h because it is to far off coarse. This is with an iPhone 15 so plenty CPU grunt.
I typically fly 50k/h to a location sometimes out of RC, fly an observation pattern and return at max speed.
On Autopilot in the observation part of the mission I indirectly manage the drone speed by small altitude changes and curves.
I have been using AutoPilot "continue on lost RC" for about 6 years with great success.
The problem with AutoPilot is the settings dialog drop down lists no longer work properly on the latest versions of IOS and it is getting harder to configure.
Do the speeds configured in the pre-converted mission not come through?
I have never had much success with Dronelink flight controlled missions when the speed is above 20km/h.
Also the link to the Airdata record of the flight, the mission stops when the notication "mode change" appears
The following is the Dronelink mission that I used to converted to DJI onboard

When I fly this mission it hardly gets started before it reports

As mentioned before the mission host was an iPhone 15
I meant can’t you just configure it for a higher speed, and then convert it to DJI waypoints and the higher speed carries over?
No, I have speed action set to 50, converted mission 7m separation highest speed in 30’s typically in the 20’s. Increase separation to say 100m speed is slower due to sharper corners at waypoints. As I increase the curve radius in the converted mission the speed of the mission increases. I can increase the curve radius to 150m speed close to 50.
I see. The flight mode changing after the drone off course message isn’t unexpected, as it changes from virtual stick back to P-gps probably (when the autopilot disengages). Getting off course messages at that speed does seem strange though, as it isn’t anywhere close to the max speed of the drone. Can you share one of the mission plans that it happens on?
The message above 2 days ago has the link to normal waypoint mission that reports off coarse.
I misread your post. You have speeds configured well about 20 kph, many getting close to the max speed of the drone, so ya, that isn’t going to work if there is any wind at all.
The link above appears to be pointing to a converted mission. The normal mission is https://app.dronelink.com/mark-pinnuck/mavic-missions/plan/gVQ2Q4sWLWtPYhLtKbZi/5AsvV7NFe1Xv511w1VOO
I am getting better at configuring DJI onboard mission to achieve my goals. I am away from home will do so more experiments. All my missions are public I have one the orbits a sewage plant that is out of Rc because of the terrain, I will try this one next, I just wanted to understand the behaviour before flying out of Rc range missions. Thanks for your support.
