I created a incognito chat for a temporary request, and when I clicked the share tab, it listed someone known as "Yaneth Gunawardena" as a person with access and the owner, even though I created the chat and its supposed to be incognito. I created another incognito chat to see if the same person is there, and even in that chat, that person is still there. I have never known anyone by that name, or added anyone to my chats. Is this just me or do other people also have the same situation? Is this considered as a privacy violation?
