I want to do this: https://developers.google.com/web/u...p-install-banners-in-chrome-for-android?hl=en Basically it launches a banner asking people to "install" your site. These are the steps they give: You have a web app manifest file, which defines how your app appears on the user’s system and how it should be launched The manifest must have a `short_name`, a name for display in the banner, A start URL (e.g. / or index.html) which must be loadable, At least an `144x144` PNG icon Your icon declarations should include a mime type of image/png You have a service worker registered on your site. We recommend a simple custom offline pageservice worker Your site is served over HTTPS (service worker requires HTTPS for security) The user has visited your site at least twice, with at least five minutes between visits. Compliant web app manifest file: Check HTTPS: Check Service worker registered: Check Site visited more than twice with at least 5 min between: Check Banner not showing . Has anyone gotten this to work on their Xenforo site?
