Why are there product ads on this expensive app? – Buy Me a Pie! - Grocery List Review

I paid a lot of money for both the iOS and desktop apps. They are probably the best grocery list apps available. However, after not using them for a year I open them up today to find there are product ads being added to my lists. If this were a free app I could accept that. But on an expensive app like this?! Shame on the developers who decided to push ads on this app. And why am I getting a response from the app developer that they want me to contact them so they can look into the problem when they must be aware the product ads exist? That’s crazy. Stop pushing annoying ads if you are going to charge a hefty fee to buy the desktop and mobile apps.
