Fiddler not working with iOS 10.3 version

We've been using Fiddler to debug both iOS and Android apps for quite a while. Recently, some Apple devices have been automatically updated to version 10.3. Since then, we can't see any feed data in Fiddler. Does anyone else have the same issue? Is there a workaround for that?

Thank you!

    What steps have you tried? Do you see CONNECT tunnels in Fiddler? Did go to Settings -> General -> About -> Certificate Trust Settings and manually enable full trust for the FiddlerRoot root certificate, including accepting a dialog that says that this will allow a third-party to eavesdrop on all your communications.

    Eric Lawrence... THANKYOU!! This totally fixed my issue, I searched all over the internet and I figured that it had to be semething about the new iOS version.

    Is this Certificate trust option new in this 10.3 version? I never knew about this option before, and I was able to use fiddler with no problems in both iPhone and iPad, maybe we should update the tutorials on Fiddler about connecting iOS devices to fiddler with this final step.
