It is also important to note that the physical device you are trying to deploy to must be listed in the allowed devices list for that provisioning profile -> you can see this here in the tooltip that pops up from your cert information -> you want to make sure that your device is listed in the "Devices" section.

You can add / remove devices when you create the provisioning profile on the apple developer portal website.
