Audiobook Chapter Skip

worrysome at badly designed Audiobook reading is in sandisk sport. . I got reply from customer service by so complicated I can’t follow with my level of skill. Tried to download update but would not open as supposed to. The thing is I had sandisk before for audiobooks and it worked fine. It finally locked up on me and I bought this one. I can’t stop a book and go back later and resume where I stopped. I have remember chapter . I can pause and turn off and start again with pause and it picks up. If I charge it the refresh afterwards  loses my place and I have to search for where I left off.I am not going to worry anymore about this . I will use it for  FM  radio and buy something for Audiobooks. Still I wonder why a company that sells these things all over the world would release something as flawed as the Sport and have no way to correct it.
