Have you uploaded the necessary icon?

Is your site configured to use HTTPS?

The requirements are outlined here:

> - your site **must be https** , this will _never_ appear if your site is plain old http
> - you must set a 512x512 png on large\_icon\_url site setting
> - Google controls when the banner will appear, the today default is: **The user has visited your site at least twice, with at least five minutes between visits.**
