After Livestream (Facebook) pulling down on the left RC stick causes the AC to "Land" very very slowly at any altitude.
RTH does not work and if low battery you may just lose your AC.

I am downgrading back to v01.04.0100 as I type this using DJI Assitant 2. (yes it does downgrade the AC and RC)

Just retested with v01.04.0100 downgrade and all is OK again.

Glad I could beta test with my 1k$ drone... do I at least get a DJI T-shirt?!?!? lol

Glad to know my decision to postponed firmware upgrade is right. Thanks for sharing.

Just to be sure...
Within 20 meters distance to the homepoint the aircraft will land where it is on RTH, you can still control the landing process.
How far away was the aircraft when you had this "bug"?
Preferably upload flight log or it didn't happen.

My ultrasound module has been reporting malfunctioning since the update yesterday from 0100 to 0200, dunno if it’s a coincidence but logs show it working immediately before the update. Downgrade through DJI Assistant 2 didn’t fix it so...

Did a FW update this morning and flew 3 batts and all is good.

I also updated to .0200 yesterday, and then did 4 flights - 2 DJI Go4, and 2 Litchi.  No problems whatsoever.

Flew 3 batteries today with no issues.

I only got the issue after ending a Facebook Livestream.
If you do try it, be sure to have a full battery and stay low.
I was able to duplicate the issue fairly easily/quickly.

You also did a Livestream in flight?

Try it for yourself. Get your own flight log. ha ~ Be safe!

I don't even have/visit facebook and I am always in flightmode during flight so someone else has to do this and I am safe.

One more issues: it doesn't RTH when it loses connection with the RC (even when I've set it to RTH)
Almost lost it but smart RTH (low battery) brought it back fortunately

Furthermore, the video transmission latency increased from 200ms to 500ms after the update

I'd like to see the flight log too. More often than not when something is blamed on the firmware it turns out to be a misunderstanding of how things work on the part of the pilot. Why not just upload the one you say you already have instead of encouraging others to do something that you claim will cause incorrect behavior?

How about DJI test it and post a flight log instead? haha ... oh wait.

Without seeing any data i would have to blame the 3rd word in the op's post.

You know I post a bug that I was able to repeat several times and all I get is skeptics and crits... your the type of people that make me not care if you know or not. ~ trolls ~
I am not going to spend more time upgrading, testing and getting a log so you will believe me; I honestly don't really care that much.

Good luck!

Actually I found your post helpful - so thanks - I'll be keeping an eye out for this now. Forewarned is forearmed.

None of that's necessary; you already have the log and it could probably be uploaded in less time than you've already spent posting snarky replies to those who've asked for it.

You shouldn't blame anyone for being skeptical if you aren't willing to make even minimal effort to provide more information that would support your claim.

Seems that I had same problem after upgrade.  Looks that I lost control with RC. The Mavic land from 30 m. I launched it and it was ok. Than I lost control again and end in a tree. Gimbal damaged, The Mavic is on the way to repair center. Let’s see, if DJI will check the flight data

I don't have the problem. Why don't you guys post your logs?

I did two back-to-back flights on Sunday morning with my MPP and iPhone 7+ flying nearly 12KM in 51 minutes using a lot of different flight modes on FW .200 and didn’t experience a single glitch. I can therefore only presume that the issue rests with FaceBook and not the FW, DJI or IOS.

The bug is produced after a live stream. I only mention this because it seems that your comment lacked the words "after a live stream".

Good luck!

I am OK with skeptics; honestly some of the comments are a bit silly; like "everything is OK after 4 flights", yet I didn't do a live stream as you had specified in the OP. *derp*

Sharing my log would give away my home coordinates.  I do not wish to share this.

I was just starting the upgrade and cancelled after reading this.  Thanks for the heads-up Bob.

Don’t live stream then LOL

And without the ability to assess flight logs this whole post is very much subjective as unable to identify the root cause based on guessing. The point is that it may be a problem with your individual drone or FaceBook rather than the FW effecting every single Mavic Pro after live streaming as this appears to be an isolated case.
