So, I, by accident, confirm a social media account as a contact's which would say about the contrast of those buttons and false click ratio (which I am sure is not the most important KPI).

Their picture gets collected and there is no way of taking that picture down or changing it. Yeah, yeah, the system will process it I am sure but it's not good enough.

I change to a custom layout in my contacts, click update I think three times and still come back to see the old layout.

I click on share feedback, only to end up in an ideasharing forum. This is not an idea to share, these are bare minimums on a Kano board.
