I have a couple of saved messages on Snapchat that I really want to delete. I've clicked on them to unsave them. It showed that they were unsaved, but they still showed up on my phone. I began to close the app all together and reopen it, turn my phone off and turn it back on, delete the app all together then redownload it. If I can get that person to delete me from their Snapchat, would it also delete the messages I want to delete?
