Deletes stories

It keeps deleting my stories and making all my stories unread so I dont know what i have or have not read yet. It also has ads that are half on my screen with no x to exit out of it. I have to close the app and reopen it. It will also glitch and close or exit out of my stories as i am reading. I love wattpad, it just needs this fixed.
