If you recently looked at Operating System Report under Browser & OS Report in or Mobile Devices Report in Google Analytics then you must be wondering what happened to your traffic from iPhone and iPad? Why are you not seeing any more traffic from these devices?
Starting May 30th Google Analytics has consolidated both iPhone and iPad into iOS in the Operating System Report. (See the graph below). iOS is the operating system used by both iPhone and iPad and hence the change to correctly reflect the operating system.
So next time you run your report keep this change in mind.
