I believe the ability to run a pure-web app on iPhone Safari - in a way that makes it look native - is a huge deal for appery web-only developers. So I believe the ability to use the home screen option is therefore critically important. And therefore I'm hoping the following fix could be interpreted in "appery language" so a mid-level developer like me can incorporate it. Thanks in advance.
**********When your page loads, add your token/data to a query string parameter in the URL using JavaScript (window.location.search). When the user saves the site to their Home Screen, the URL is used as the key. Your JavaScript can easily extract the query string parameter you sneaked in earlier if you detect that you are in Home Screen mode (window.standalone). This should work forever, except the value in the URL will also be there forever.
