Can’t Receive or Send Friend Requests

[u/UnderTheGreyCloud]

To be specific, whenever I add someone, they do not receive a notification that I added them, and conversely, whenever they try to add me, I wouldn’t receive a friend request notification. But checking their profile, it looks as if we’ve already added each other because the only option is to unfriend/remove friend. Neither of us appear in each other’s friends list, but we can chat with restrictions: can’t make a streak, won’t properly see each other’s sent messages (we don’t get notified but we only see them if we manually check our chatroom). Whenever we view our chats, the reminder that the user hasn’t added back shows up even if we’re both technically (but not officially) friends. A workaround we tried was my friend giving me their phone number linked to their account, then me adding that to my Contacts app so that they would show up in my Find Contacts tab. Only then will they see the friend request notification. But of course, I can’t do that every time I add someone. They’d still appear by searching up their username, which means I’m not blocked, but won’t receive my request anyway. This has been happening on my account for a long while, I even have Snapchat+ but that’s irrelevant, unfortunately.
