You will note that in the Organizer's preferences, there is an option to automatically rotate jpg and tiff files. There is no such option for HEIC files. I'm not sure whether this is an Apple or Adobe problem. ISTR that there was a recent Apple update that dealt with the issue of rotation of images. In any event, I plan to bring this to Adobe's attention and hope that it will be dealt with in a future version. I would not expect an update to Elements 2021.
