Charging service fee and never provides updates – Duck Donuts Rewards Review

They began charging a $1 service fee for the app and they don't provide any meaningful updates. I've submitted feedback multiple times to which they respond, but don't actually implement. How can you keep releasing new flavors but never change the list of fan favorites? They never implement an option to select seasonal flavors. It's incredibly tedious to build your own donuts rather than just let me select the seasonal donuts.
