I have the same issue.
I have confirmed it on my iPad Pro 11inch (3rd generation), but it happens 100% on the iPad Pro while it happens sometimes on the iPhone.
So far, I've been able to work around it by launching the app and then connecting to the drone and controller, but I hope DJI can solve this issue.

Sorry for the machine translated English.

@muratatakashi Please tell me how to reproduce this bug, thx.
