In the meantime we were investigating the case with our developers and noticed that this could be related to the fact that not more than one app can use the same permission (hence the SDK) at the same time.
This means that if users installs any other app which is using DJI SDK we are not able to install our app for the store.
- Do not install more than one app that is using DJI SDK on your device, e.g. Ctrl+DJI and another app.
As a side note, you can have Pix4Dcapture, Ctrl+DJI and DJI GO app installed on the same device at the same time.
We are waiting for the new DJI SDK release that will most probably solve this issue and also actively working on providing a permanent solution on our side.
Make sure to follow this thread as we will post the updates of the situation here.
