In some of the inactive groups, I see a message that says you were removed, but I can see other people that are still in that group.  I just can't send messages anymore.  I know that this is different from xyz removed you where xyz can be one of the admins.  I am assuming that WhatsApp removed me from these groups where it says you were removed.  What could be the reason for WhatsApp removing users from groups?
Why do I get a You were removed message in inactive groups?
whatsapp
