Hi, Can't connect my OA camera to my LG phone or Iphone to activate. It says now only 3 more times?  Wifi/bluetooth shows the camera connected. But when I try to connect to the Mimo app it won't connect. The phone shows up on the app, but won't connect. On the Iphone the camera pops up with wanting to join the network with a huge DJI code and to accept it reject it. I accept it but won't connect, says can't join network? On the Android phone basically says the same thing. I uninstalled and reinstalled numerous times,  changed to airplane mode and all the other ideas in this forum and others.  
Then only thing I noticed on the camera was it only had 2.4 g. I updated the firmware and it still only shows 2.4g?

Any ideas....

Thanks
Micky

I have the same problem. Just bought the Osmo Action, and have tried severeral times to activata with my Iphone, but evere time it comes up with "Activation data error".

What can I do ?

Exactly the same problem here. I've tried scanning the QR code too which takes me to a web page that isn't working. Perhaps DJI web or activation servers are having issues?
