Not getting Webpushr Optin on Mobile

I set up Webpushr on my website bloggingidol.com. After installation & setup, I got an opt-in notification on my desktop.

But I didn’t get a similar opt-in on my mobile. Is there any specific setting for the mobile option? My website is on WordPress and I used the plugin method to set up Webpushr.
