Since upgrading my iPad software last night, all of my purchased apps are no longer showing as 'installed' when I log into the app store on my iPad, or on my iPhone for that matter. I have tried downloading a couple of apps again, but this doesn't solve the problem either. Anybody else with the same problem? Thanks Update: have just noticed if I click on an app that I already have, it says 'installed' on the next page. Never done this before.
