Since installing IOS 9 last week I'm now well over my usage limit.  My bill says I used £26 worth of data today alone,  sitting about 20 feet from our office wifi router

Sounds about as good as going for Lightroom mobile.  its just as well I was on an unlimited data trial for a month, or I'd have used 3 months allowance in the first 3 days of having it.  Just what on earth was it doing?  I got the impression that it was loading my entire lightroom catalogue onto the mobile (which wouldn't have fitted anyway, as my phone doesn't have a 500Gb SD card in it...)

This is a feature that should have not been switched on by default. At least it getting a lot of publicity now.
