When I press on some message to forward it, it shows me Random usernames of contacts I don’t know. And it even shows some Mobile Numbers I don’t know. For example, one number starts with +964 that’s Iraq. I’m from Europe tho. These contacts and numbers are from all over the place.
Edit: This only happens on Signal Desktop. If I try to forward a message on Android it only shows my Contacts. And none of these unkown ones.
Could it be that these are spam numbers that tried to reach you at some point but were blocked before they could?
