I'm using an iPhone 7 Plus with iOS 11.0.1
I have the most recent download of DJI Go4 (4.1.14)

- I start the DJI Go4 app, it opens OK.   

- I go to the 'review' section (Where it shows growth of value, distance travelled etc).

- I select any previously logged flight.

- The logged flight opens showing the background as a street map only.

- If I try to change to a topo map.. (Topo alone or Hybrid), the program crashes and disappears from the screen.

- This doesn't happen on the live flight screen.  I can choose any map there.  It only occurs on the flight review screen.

I've 'rebooted the phone, but the problem persists. Anyone else seeing this?

Have you tried to re-install the APP? Please upload a short video of this, I'll forward to our engineers for review.

Hi DJI Susan

OK...  I removed the app, then reinstalled it.  I logged in again and re-synced the records.  The crash still happens.   As you requested, I uploaded a quick video to Dropbox.

Just to add..   It crashes on all my flight records when I try to select a topo map and not just with the one I chose.

As a follow up:

DJI Go4 version 4.1.15 just became available tonight.   I installed it and everything is OK now.  I can access the topo maps in the flight review screen.
