Book Cover is Actually Horizontal But LibraryThing Rotates It

I've seen a few topics where the desired book is vertical and the orientation gets rotated to horizontal. I have the opposite issue -- the book is horizontal and LibraryThing rotates it.

I am using the LibraryThing app (Android). I have tried it both using the camera inside the app and selecting from my photos. I have also cropped it (I know other topics suggested editing it.)

And now the app is showing the book cover oriented correctly.
