I would appreciate it very much if some of the experienced users of the app would consider joining this chat but do so using the link that I can send you by PM --
I want to do this because as of this morning Mardee and Emily and I have demonstrated that we can see each other's posts in the group chat without having them be in my contacts on my iPhone.
In case that is a fluke, I'd like to try it out with a few more brave souls.
When Mardee used the link to join the group chat, as the owner/admin of the group chat I got a message asking me if I wanted to block or add her to my contacts -- I clicked on neither button. She is still in the group, and as I say, we can see each other's posts and each other's names and phone numbers, but Mardee is not, I repeat not, in the contacts/addressbook of my iPhone.
I was interested, and am still interested, in seeing if someone can join a group chat without being in the contacts of the owner/initiator/admin of that group chat, and it appears to me so far that that is indeed possible.
My interest has to do not with concern about whether members of a chat can see the number or name of other people in the chat, but whether Meta must have full access to the contacts on the phone of users of the WhatsApp app. That is still TBD.
I realize that this does not align with what several commenters have said here on this thread. All I can do is tell you what is happening -- Mardee and I are chatting in a group chat in WhatsApp but Mardee (neither her name nor number nor email address) is in the contacts list on my phone.
Let me reiterate again further additionally:
When I say above
" I clicked on neither button. "
what I mean is that when WhatsApp informed me that Mardee had joined the group chat and asked if I wanted to block or add her, I did not click on the block button or the add button. Mardee remains in the group, can chat with other members of the group, but does not appear when I search or scroll in my contacts list on my phone.
Emily, by contrast, does appear in the contacts list of my phone, because I added her using the '+' button in the app.
