While playing Walking Dead Saints & Sinners, during mission 1, I am not able to go through the pages to retrieve the key. I have re-tried the mission 3 times, and every time I can not navigate to the previous screen in the bag. I even tried removing items from the page to get to the previous page without success. The arrow buttons do not navigate to the previous page. Are there any solutions to this problem?
I finally figured out that using the trigger on the arrow buttons switches the pages. Before I figured out how to work the backpack, I just finished the first mission by avoiding storing anything else before getting to the lock for the key.
