Our company used to be able to distribute in-house apps on a simple internal web server. However since Apple update the iOS to version 9, since then it no longer work anymore.
Once a user clicked on "Install" confirmation after that the alert pop up with, Title "Unable to Download App" Message: "Your App" could not be downloaded at this time.
I don't know what change that I need to do to make distribute in-house working again.
Thank you in advance.
