iOS Enterprise App release (some low-version system) can't install to the latest version of App-cache causes

When you publish an enterprise app on your website, you've been tested to find that there's a problem with a low-version iOS phone that has some older apps installed: A sweep code overlay installs a new version of the app, and the app is still installed on it. This results in some users not being able to update to the latest version. The detection is due to the mobile phone cache: There are two main parts of the cache, one is the page download plist resource path, and the second is plist to the IPA package download path:

First, the main process of publishing enterprise application is as follows

1. Use Enterprise Certificate packaging to apply the IPA file and publish it to the resource server;
2. Generate the Plist file, set the IPA file path in the file configuration sink, point to the previous step to generate the IPA file download path, publish the plist file;
3. Create download page, add <a> label download Install button on page, href point to Previous step summary plist file URL, publish page;

Ii. adding random characters to the download path prevents the cache from downloading and installing the new version of the app

1. Add a random string to the download button link
2. Add a random string to the path of the plist file download IPA file
