The best way to deal with this uncertainty is to order the items by priority.Īs we mentioned in previous chapters, PWAs on iOS and iPadOS are only installable from Safari other browsers are not able to install PWAs in the home screen. A full discussion per platform is out of scope but below you have an idea of how it works on Android and desktop. That means that you can't rely on these shortcuts to appear consistently, and even if they appear, you don't know how many shortcuts will appear or if the platform will ignore the icons as its at the discretion of the browsers.

It takes an array of members with the following properties: name : The text that will be shown to the user, typically in a context menu. Shortcuts are defined in the shortcuts member of the manifest.
