Portrait Photos Gets Rotated When Posting from iPhone

Portrait Photos Gets Rotated When Posting from iPhone.. please see attachment. any solution please?

Would you please send me the original photo from your phone.

I don't seem to have a local copy. I took the photo as I was doing a test post. If you rotate it 90deg clockwise..that's the original portrait photo.

If you take a portrait photo from a phone as you post, likely you'll get the same result.

I did another test with this attached photo..same result

I have uploaded your image on a listing and all looks like ok. Please check my screenshot: https://prnt.sc/sd3ma3

Did you use a mobile device? I used iPhone. It works fine when uploading from PC.

Any idea/advise on what's causing this please?
