I have a problem but it has nothing to do with my Facebook account. I just got a new iPhone 8 last week new number and everything and it seems some lady had my number before me and I'm getting text messages from her Facebook account. is there a way I could disable or block those messages coming into my phone?
I'm not sure if a notification text is sent to confirm the changes as I've never tried it myself. I recommend posting your concern on the Facebook Help Center. They may be better suited to answer your query.
