In the Google Photos app, the menu is inscrutable. For example, to rotate a picture, it's:
Edit - Crop - and then a symbol for rotate.
There's no way to rotate a photo without selecting "Crop" first.
It wasn't always like that. It happened with an Android update quite some time ago. For the life of me I can't figure out why.
I should specify that I'm referring to the mobile app. I don't think I've ever edited a picture with Google Photos on a Windows desktop or laptop, so I only think of the mobile app. I'm using a Google Pixel 6.
