There is a guy whose phone number I don’t have, and I’m not friends with him on Facebook. He sent me a message on Facebook, and it went into my ‘message requests’ folder rather than my inbox (which I understand is normal when someone you aren’t friends with sends you a Facebook message).
When I searchEd for his name in my iPhone, I got the entry below - his name (which I’ve cropped out) then ‘instant message (Siri found in messenger) and then a series of digits below which I have blanked out and which I understand to be his Facebook ID).
However, when I search for the name of anyone else I’ve spoken to on Facebook messenger, this kind of entry does not come up. Siri only locates them if they’re in my phone book or email.
Does anyone know why this is? Is it something to do with the fact that this person was a non Facebook friend who messaged me?
