Can't upload screenshot for review for In-App Purchase in iTunes Connect

Question

I created an in-app purchase, and the only thing I need is to upload a screenshot. The problem is that every time I try to upload it, I choose the file, click save, it loads a bit and then the popup disappears with NO screenshot uploaded and no error message.

I have tried with a lot of images, all of which were at least 640x920 pixels and at least 72 DPI, like in the requirement. But it doesn't take, and I don't know what more to do.

Is there something that I'm not aware of?

Answer 1

Had the same problem. The magic for me was being patient. After you select a file it actually starts to upload it in the background (even though it didn't show anything in the UI for me) so you have to wait for it to finish and show the thumbnail before clicking "Save". After I figured this out, it worked fine.

I had this problem. In desperation I tried uploading in Chrome rather than Safari and it worked. I've never had a problem before but they have just redesigned the site so something's gone awry (maybe my content blockers were getting in the way).
