How can I delete multiple message threads on iMessage at once?
Every time I want to clear my iMessage threads, I have to go through them one by one and delete them all. This is time-consuming and annoying. Is there a way to delete multiple threads at once? Also, as I go through, I often make a mistake and delete the wrong thread. Is there a way to retrieve the thread, or is it lost forever?
