I received my OSMO 3 today. The red button stopped working after only 5 mn...I disconnected BT, up again... Same problem.

Another issue with the trigger, sometimes it does start the tracking, sometimes it does not ?

Thinking about returning that product thanks to Amazon

Hello and good day philgib. I am sorry for the trouble this has caused. This is not the experience we want you to have with DJI. Are you able to post a short video footage of the said issue on your new DJI Osmo Mobile 3 for us to see and to be able to assist you further. Thank you.

Thank you for that. Looking forward to that stable version.

Hang on, this goes back a couple of months.  The update referred to came out weeks ago, so you should now be having no further issue of the kind you describe.  Are you still having a problem?  Are you sure you are using the latest version of the app?

I can confirm that it is working correctly with new firmware. Great job guys. Cheers.
