Hello, we recently reported an issue we experienced while using offboard mode after going to PX4-Autopilot 1.15 which we never had before the update. In short, the drone once started rapidly descending in offboard mode, only being caught by manual RC intervention / position mode. The second time the issue also started in offboard mode and even though the drone quickly switched to position mode it kept going down, eventuelly crashing in the ground. More information can be found here Offboard Mode Issues on PX4-Autopilot 1.15. As we don’t know how to progress with this issue we would be glad about any help we can receive. Thanks in advance!
