In Google Cloud Platform I have enabled the Apps Marketplace SDK to publish a sheets-on to Marketplace.
In APIs & Services > Apps Marketplace SDK > Publish I am unable to upload a screenshot. I keep getting Not saved.
see here:
I am using the correct size screenshot and have tried many different sizes and image types. ex. 640x400, 1280x800 all the recommended sizes. I have used png and jpg.
I can't click the publish button until a screenshot is uploaded. This is weird because I was able to upload an image for application banner without issue (as shown in the image above).
Any ideas why I am getting this Not saved message?
