Your phone has an accelerometer in it so that it knows which way is down. Instead of using this knowledge when encoding the photo to JPG, it always encodes the photo the same way, but tagged with metadata saying "When you display this photo, rotate it X degrees". You need to either take the photo with your phone in its natural orientation so it doesn't need that metadata tag OR you need to open the photo in editing software that ignores the metadata tag, rotate the photo to the correct orientation, and save it.
But if I took the photo with the phone vertical, facing the location, isn’t that its “natural orientation”…
At least that explains why it uploads the right way up, but then flips when I “publish”, I suppose! 🤷🏻♂️
Counterpoint, though: I don’t have this problem on Facebook, Twitter or Instagram, though (all mobile web, not via their apps) - literally only here, so far…

Oh, well that’s very annoying…

It could be that those sites automatically remove the metadata. You can download the pic from Twitter or wherever and then re-post it here.
