Impossible to upload image to Google play store

Question

I can't upload images to the Google Play store in order to put my app in production.

None of the images can be uploaded, I checked 50 times, the size is good and I tried as png, jpg, jpeg, etc without success.

Here are the screenshots of my tries:

What could be wrong?

Edit: I have the same problem to upload the apk and the problem seems to come from CORS policy but deactivate it does not change anything...

Answer 1

The solution until November 2, 2020 is to use the classic Google Play Console in private mode. There, image uploading is working as intended.
