Uploading screenshots to iTunes connect for iPhone 6 and 6+

Question

I'm trying to upload screenshots of my app on iPhone 6 and 6+ and I'm getting a baffling error message:

"One or more screenshots are the wrong size..", see the screenshot below

However, I have checked the apple website and the required size is 750x1334 and 1242x2208

In an attempt to prove I'm not going nuts, screenshot of the properties below.

What am I missing?

Answer 1

1. Open your screenshots in Preview application
2. Go to Tools -> Assign ProfilE
3. Choose sRGB IEC61966-2.1
4. Press OK
5. Then submit your screenshots to Appstore Connects

its fixed for me!.
