For those of you (like me) who have found your camera will not turn off-
I found that the app keeps the communications with the camera open, and that's why the cameras power light stays on.
I found if you navigate to the phone or tablet's settings / apps menu and scroll to the Snapbridge app, you can force stop the app and the camera will shut down.
This method is much better than any other means to accomplish this seemingly simple task of turning off your camera, but you would think the developers would at least add a "shut down" button to the app to do this instead of forcing both the camera and device to remain active.
If anyone has an actual e-mail address to the developer (the listed e-dress in the Play Store is a dead account) I would love to have it. Probably best to PM it.
Thanks!
