Welcome to Connect and congratulations on your first post,
All you can do is to make sure your email settings are checked for rewards on this page: https://www.google.com/localguides/settings
The handing out of rewards have pretty much been phased out in my opinion. So waiting and hoping for at reward will most llikely lead to dissapointments.
I find it very rewarding to know I help a lot of people with my edits and photos. I love following how my contribution stats grow over time. You can also view this community as a nice perk where you can get to know fellow LG from around the world.
