Documents 5 App Issues

This app is a nice app to copy links from basically anything and paste links for downloading music to the Documents 5 App. But, theres something that constantly happens that always bothers me when it happens. And that is when I play songs and it doesnt start it from the beginning, but instead it starts it at any random part like in the middle of the song or the end of the song and keeps doing it until I actually go into the app and scroll to the beginning part. In return, its just annoying, inconvenient, and aggravating. Another issue that really bothers me is when I listen to a list of songs, somewhere along the way, when the next song comes on, it wont play at all until I actually press play. If these problems are resolved as soon as possible, that would be greatly appreciated. Thank you so much!
