This is likely code in conflict with EXIF rotation values, and we hit various situations where we need to trust the EXIF and situations where the EXIF has been modified in such a way that we can’t. I saved the photo without EXIF data, uploaded it to the Encounter, and I was able to draw what I think was the intended bounding box after uploading it as a test to the Encounter you reference above. If you hit this frequently, it may be worth digging deeper on our side to understand the nature of this conflict and see if it is a case we need to support, but EXIF is the not-actually-a-standard for which we find a lot of weird edge cases, especially around image rotation.
If infrequent, saving the file without EXIF is a good workaround.
I figured it was something like that. With the volumes of images we see in some sightings, we don’t always catch issues like this pre-upload but we should add it to our list of “ACW Image prep Tips & Tricks”.
