P: Camera feature gets stuck in portrait orientation even when rotated.

Hey folks, trying to navigate an issue where my phone display turns off with the pro camera in Lightroom pulled up  and when my phone is reopened the display is reduced to the size it would be if the phone was being held portrait. This persisted even when rotated, after closing and reopening the app. I was able to reset the issue by redownloading the app for a short period before the issue reoccurred. Pleas asssist with any advice on how to resolve. I love the pro camera feature. It provides a lot of basic control over the cameras in an iPhone. 

Thank You!
