OK we definitely need clarification from Revolut here. @anon33247966 could you assist please?
Prior to reading this I went in and changed the slider to the left to make it grey. This is consistent with all the other stuff in the same screen. Left (grey) means off, right (blue) means on. And the thing being turned off/on is the thing described in the bolded heading: “Marketing emails”, “Marketing pushes”, “Payments with friends”, “Targeted marketing”.
It is completely inconsistent if the “Targeted marketing” has to be ON to opt out.
