title: Deploying Tizen app to Gear S2: Non trusted certificate is used
body: <p>After getting Tizen Studio to work, I am (unsuccessfully) attempting to deploy a sample app to a Samsung Gear S2. The app is one of the samples and I've set up the certificates for use on commercial devices as explained in the instructions. </p>
  
  <p>When I select "Permit to install applications" I get the correct success response and I can also see that the <code>device-profile.xml</code> is on the device with the correct DUID.</p>
  
  <p>However, attempting to deploy the app (both from the IDE and via sdb) still results in an error:</p>
