Stop unwanted notifications on the production app

I get many notifications from MoneyCoach app.
One says "Thanks for using MoneyCoach so much. Let us know what new features you want and we will implement it". Do you really have to do this on a production app?

This seems like I am beta testing. On beta testing or test pilot versions, those notifications are fine. But I don't understand why those notifications are required for an app in production.

Also, even though I am a premium user, I still get "50% off for premium" notifications all the time. You don't have to show that to premium users anymore.

This is a great app, but I am getting way too many unnecessary notifications. I don't want to block notification for this app either, because I'm not sure if I will miss important ones such as reminders to log the expenses.

Atleast give us an option to block marketing related notifications.

I'm a normal user, who doesn't want to improve this app with you guys, instead I want to use it. Think about normal users who actually use your app rather than people who are testing it.

This is a great app, infact the best feature rich expense logging application I have ever used. But too many unwanted notifications has been a real issue for me for the past few days.
