profiles:manage:devices does not save changes

I run ios profiles:manage:devices, choose an app, uncomment a device, save changes, and close the file.

The command line shows Successfully managed devices.

But then when I run ios profiles:manage:devices, the device is commented out again.

Update: After going to the web site, and adding the required certificate, it now works. I think the problem may been because I had recently renewed by certificate, so I had to add that first.
