I got an email tonight stating that my Amazon Grocery List was now my Alexa shopping list.
I have Alexa shopping turned off. Should not be possible, but they did it anyway.
So I looked at the rest of my lists. They had turned on Alexa manipulations ( buy / change /delete ) on all of them.
I had to select each list, pick manage list, check “no Alexa Access”, then click save on each list.
Most annoying. I have provided feedback to this effect to Amazon.
If you use Alexa, you may want to check permissions and such.
