Where do I manage push notification settings in the xfinity app

I love getting rewards from xfinity, but the push notifications from the mobile app are not consistent. More often than not, if I get a notification from the app, it is hours after the rewards have dropped and they are no longer available.

I just got an email today advertising what to expect this week, and a "link" to enable notifications. The link takes me a page with a QR code to access the app. I use my Android phone, scan the code, open the app, but nowhere can I find how to manage my notifications. When I search for instructions, they say open the application, go to the Account tab, select Account Settings, and tap Notification settings. When I follow those steps, I do not see an option for Notification Settings.

Where did the notifications settings go? I would like to see what I have set up for my push notifications, and make sure I get more consistent (and timely) notifications for new rewards.

Thanks.
