can you share the mission, so we can take a look
Apologies this is the correct mission:

Don't know whats going on Armond M, but something is definitely broken

In the settings, you have set the maximum rotation rate at 2.0 instead of the default of 20.
Not sure why you changed that but that is not allowing the drone to turn fast enough.
On a different note. Once you have set something like a POI, the mission will continue to follow that until you tell it to do something different. You don't need to keep repeating it in all of the other waypoints, or add a path action to tell it to point to the POI. All of those are redundant.
Finally, when sharing a mission plan, I would recommend using the viewer only option.
Try this plan - I think it gives you what you need.

Good catch there Barry 👍
Hi Barry,
Thanks for the feedback. Yes that seemed to be the issue.
I'm curious, why would that cause the drone to lose track? I thought it worked interpolate the path by showing the velocity down in order to be able to rotate and keep the POI lock. Shouldn't it theoretically behave that way?
The reason I reduced the rotation speed was in order to create a smooth and show rotation for cinematic style flying. 20 degrees per second is a pretty aggressive rotation speed for that's sort of video capture.
What do you recommend to resolve this issue?
A few other things you should know regarding many of the default values you changed. The altitude tolerances you set to -3’ and 3’ may cause the mission to fail. I’d change those back to the default values of -15’ & 15’ as they have been tested for years to work without issues regardless of which drone. The same issue may arise where you have the distance tolerance set to 5’ and the altitude set to 4’ at the first destination waypoints start. If it can’t reach that first waypoint destination within the 5’ distance or the altitude within 4’ it will fail. Depending on which actual drone is being used, any winds or other environmental factors it can affect the accuracy of these drones during flight. The mission may run but always best to leave all the default values as none of those tighter tolerances will affect how the drone flys during the mission and it will be no more accurate. There is nothing wrong with using Expert Planner mode but be aware of the possible issues. Until you understand how they will affect the actual flown mission I’d keep all of them at the default values. I have rarely changed those defaults values and I’ve flown a ton of missions with a good amount of flight time. Also the mission preview is just an estimate and has no way of knowing which drone you are using. So when flying any drone in the real world they will vary based on which drone it is and what you have set in the drones firmware. The Yaw (rotation rate) and smoothness as well as the Gimbal pitch speed and smoothness under Normal “P’ mode will affect those functions during the mission and can make a big difference.
Good luck and enjoy.
If you slow down the rotation rate then the drone cannot turn fast enough and it loses track.
In some cases the drone will adjust the speed to match the parameters - e.g. mapping. You can see that in operation in this video https://youtu.be/wDdR3Tp9g-s
But that is not always the case. As Mike mentioned, most of the time it's better to leave the standard parameters in place and, if you do decide to change them, check what happens after before moving on to other changes.
Thank you all for the feedback and help...much appreciated! :)
