The only setting I can find concerning the appearance of the shopping menu is (Hide/Show) suggestions, I have that feature set to Hide. This does not get rid of the pre made list.
I opened it today and all the suggested items were marked to be added.
Developers, please give users the options to turn off changes to the alexa app.
I prefer it simple also, it is one of my most used feature of the app.
Thanks for your input.
