It sounds like you might be trying to fly home manually. Please let the app fly the aircraft back and land it. If you need to make adjustments right before landing you can do so but if you take over on the way back things will get out of sync.
The other thing to do is use the Manual Restart feature if you see that the blue verification line is showing the flight is not going where you expect. Then you can tap on any corner waypoint to restart there instead.
