Moon displays inverted in southern hemisphere #2571

Moon phases in Trail Sense appear inverted to us southern hemisphere settlers. The upside down moon is explained in this NASA article.

But we don't need NASA. I can share the view of the last quarter moon from my window when I looked up north this morning.

In the screenshot above, we can see the moon illuminated from the east and the sun arrow pointing where the sun is located in that morning.

But this is not what Trail Sense displays for the AR moon.

In this second screenshot, we can see the moon displayed upside down and illuminated in the opposite side of the sunlight.

It shows inverted in this screen below as well. At least to those of us used to find the moon looking north.

Correcting the displaying of the moon here would be right too. The graph displays the sun and moon on the same vertical line always and thus there won't be illuminated side issues here tricking the mind.

Thank you, I will look to adjust the moon image rotation for latitude
