Beta Hub failed to fly

I have setup a simple mission with my Phantom 4Pro and Beta Hub, but have consistantly got a failure message after loading on iphone or ipad - Uploading Mission…
Upload Failed: Invalid parameters in waypoint. I the created a similiar mission with the old Hission Hub with no problem. Philip

Also tried same missions (Beta and old) with my Mavic Pro. Same result.

A similar mission but obviously NOT the same
Most likely the distance between 2 consecutive waypoints is either too small or too large.
and:
Did you choose the correct Drone Model in the new Hub ?

Instead of guessing, would you be willing to share the troublesome mission.

Thanks, I think distances are OK and Drone model (Phantom 4 Pro) was set in settings. I’m happy to share the mission. How do I attach or send the file?

Mission > Share > Set to public and send us the url

Set mission to public. Now how to send URL? Litchi Hub. perhaps

I can’t see anything wrong with the mission you shared.
You updated it 2 hours ago, what did you change ?

I think the only change would be making it public. But I have had the same ‘no go’ result with previous Beta missions.

I moved the mission to my location (in the “old” mission hub) and it starts just fine with my Mavic Pro.

Just tried opening the same mission in the old Hub and saved it there, but same failed to fly.

Sorry but this is very confusing to me:

Meaning you could not ?

Meaning the mission was uploaded without errors to the drone, but the drone would not fly ?
Did you get an error message ?

Perhaps you are in a No Fly Zone ?

Not in no fly zone. Error message as the mission was started to up load to the drone.

We found the issue internally which I believe only affected the Litchi app on iOS. To fix a flight that wasn’t starting, simply modify it on the new Hub (any modification) to trigger a new save then it should work.

I assume you mean I should modify the mission in the iphone / ipad app before trying to load and fly?

No. He said to modify it on the new Mission Hub.
