Autopilot strange behaviors

[iPa64]

Hi,
for now, I have only bad experience with Autopilot or at least strange behaviors:

- After disangage mission, tried to use RTH, but strange behavior of the Mavic, it rise with speed variations (wave), so I aborted RTH.

- Tried Zipline mode, it reached point A and nothing else, stay there !!! Is there something to do to send it to the next point (B) ?

I have tried to disable LCMC but without behavior improvement

What's wrong ?

Autopilot 4.1, Mavic, iPhone7

Ok for Zip Line you have to press "Flight B point B"
Still the RTH issue
And one other question, someone can confirm that we have to disable LCMC in Dji app to get all feature working in Autopilot ?
