Please fix

I really love Wattpad and have been using the app for years. But now Im having a problem that I didnt have before. Whenever I read a book in my library then shut off the app, when I come back the bar that usually shows how far you have gotten into the book, is empty and the book starts from the beginning again and not where I left off. I dont know if anyone else is havin this problem but I would like if fixed. Thank you
