Lately I'm unable to select more than one image to send, as soon as i scroll up or down them it unselects my previous selections, also last week it appears that some of my chats with people would suddenly disappear, the entire chat thread... It would just clear the chat thread and the thread would disappear from your inbox however the user would message again and it would start a new thread, I am certain I did not delete and I'm positive that the user did not block and unblock me.
