I'm letting people know the issue and how to resolve it. And it is a fact that if the Life of Website members skipped the picture, it would get rotated upon approval.
Here, I am letting you and SLS know what the issue is and how to resolve it: it is NOT a "compatibility issue between our site software and some devices", but rather the "site software" is deficient in that it does not correctly uses the embedded meta information in the uploaded pictures (as spelled out in apple thread you referenced). Update, or replace, the software that handles the uploaded pictures and it is a fact that the pictures will appear correctly, without any members or support staff having to intervene.
