No problem on my iPhone, updated OK, but my iPad where I deleted it and tried re-installing is showing in the App Store as 'installing' but the progress bar has not moved an there is no icon on my springboard. Normally when you select things that are installing they pause and you can then restart them but this one does precisely nothing. I've left it over night, I've tried a hard reset and it is still showing the same, I can't cancel it or re-install, any ideas?
