One design decision to make sure is correct. I believe we should not show the opt out for existing users, as they saw the first opt in prompt already

Well existing users will not get this popup because I'm using the same setting value that opt in users got. Their settings will stay untouched and this popup won't appear since existing users already got a chance to chose what they wanted

we had some small UI concerns. they are low priority and can be fixed separately
