Thanks! We were able to install the proxyroot.cer....the problem was we weren't actually recording when trying to access the url to download the cert. We followed all of the steps recommended in the previous post (with success) except for the firefox proxy-browser settings, we just haven't gotten to that part yet.
We were able to generate a script for the linkedIn native app with no issues. We're trying the DeVry Mobile App and still aren't able to get past the log-in. We tried this all with port 443, assuming our issues were due to SSL authentication. We're going to try switching ports to see if that helps.
Any other suggestions are welcome!
