I'm on Android and also not able to get app notifications. ??

Oh, for choices on what/when/how for notifications, go to your Preferences in the main menu.
I come here 2-3 times a day so turned off the notifications, just more email clutter.
Again, i run Android on a 10" Samsung as my only device.....just download the app.

I use Android on my $24.99 burner phone and my 10" tablet, both have the app....just download it!

As far as I can tell there's no support for notifications on Android yet.

A screen icon can be gotten by downloading the app. I don't know about notifications. I get email notifications, but haven't seen how to get notifications directly from the site/app.
