I select a portrait image with the launchImageLibraryAsync of expo-image-picker.
I apply a filter on this image, and then save it.
On iOS the orientation is not kept. The image is saved with a landscape orientation.
The orientation is kept when i take a photo with the camera with launchCameraAsync.
This is an iOS only issue. The orientation is kept with both library and camera selection on Android.
I have an expo with EAS environment.
