I was confronted one morning recently by a very frustrated daughter of mine who was complaining that the home WiFi was playing up again, and that she couldn’t connect to either Apple App Store or the iTunes Store from their iPad. The symptom was quite curious, because the applications appeared to display correctly momentarily, and then the message “Can’t Connect to the App Store” (or iTunes store) appeared after that. Very strange.
In typically careless fashion she hadn’t backed up or synced her iPad in months, and the system software was 2 versions out of date, and so I suggested she do all of that housekeeping and once that was all done, come and see me again. Well she had to go out to do some shopping, so it fell to me to go through all of these remedial actions, none of which appeared to resolve the issue. My other Child’s iPad was working fine, so the mystery deepened.
