I have Android 13. I noticed that if we don't set the iOS Startup Image (start screen for Apple), we can't install the PWA application. Recently there have been problems with the configuration of the iOS screen, so I suggest moving the meta tag
<meta name="mobile-web-app-capable" content="yes">
<meta name="apple-touch-fullscreen" content="yes">
<meta name="apple-mobile-web-app-capable" content="yes">
before
{{if \count( $apple )}}
After this procedure, the browser detected the application.
