I have been using the infamous modify_pList.sh hook to allow http traffic on iOs9. Just recently I updated my provisioning profile in the credentials area of the ionic.io platform site, after I updated the cert and profile and sent another pacakge to the ionic servers it successfully built my application however all http traffic stopped working. I added a hook that had previously failed on every attempt of using before to see if my build will fail and it did not leading me to believe that my hooks are no longer being executing on the server.
Iv tried to using ionic hooks remove & ionic hooks add to try and get it working again but with no luck.
