Not Receiving Notifications Despite Settings Being Enabled
To change a couple of things if you want to receive notifications in real-time.
The first thing would be changing the "Daily Digest " option to "As Activity Happens".
Also, you may want to make sure to follow the Members and Hosts who you would like to be notified about and toggle on "Activity From Members You Follow" or "All Posts". This will allow you to receive all the notifications correctly.
You can follow members directly from the member list or by visiting their profile.
