The Keep&Share mobile website is an optimized version of the Keep&Share website that you would access on a computer. The mobile website will be formatted to fit and function on any mobile device such as a smartphone or a tablet.
If you want to make changes to who you've shared items with in your account you will first need to navigate to that item (ex. a calendar). Once you are viewing the item you want to share you'll need to tap on the single downward arrow towards the top of your screen. This will pull up the Share Control and then you can make your changes and save them. See the image below:
