How do I uninstall and reinstall my app?
If you’re having no luck with the suggestions above and you decide to remove and reinstall your app, all you need to do is press and hold on the app’s icon and tap the ‘x’ (iOS). Alternatively, under Settings, Applications and Manage Applications you should see a list of your apps, where you can remove any misbehaving ones (Android)! To reinstall your app, simply locate it on your relevant store, and tap ‘reinstall’ or the cloud icon (iOS). You can also see a list of previously purchased apps (but make sure you are signed with the same ID or account you used to purchase the app originally).
You can find out more information about reinstalling apps, or finding your previous purchases, using the following links.
