maybe the problem is a bit that the same verified-icon is used for two different purposes - verified contacts and verified chats.
we could use two different icons, however, this might be even more confusing - having a verified-contact-icon in 1:1 chats and a verfied-chat icon in verfied-groups. and theoretically both icons in a group with only one contact. at a first glance, i would not like that
i think the blue-checkmark should guarantee some kind of extra-verification - and this would be mitigated if we show a similar icon where no verification-guarantee can be given.
as a workaround - if you tap on the title bar in an 1:1 chat, there is the text “verified contact” shown.
maybe we should drop the usage of the verified-icon for contacts completely - there is already the idea to show the text “verified by NAME” in the contact lists, maybe this is sufficient. the icon would only be used for a verified channel then.
lots of maybes
