G Suite Marketplace SDK [Publish] button always greyed out?

Question

My app is finally published in the G Suite Marketplace. However, I need to update the banner image as it's blurry and the [Publish] button is always greyed out. What is missing from this screenshot?

Answer 1

Go into the OAuth Consent Screen, under "APIs and Services" and check that everything is filled in there too. The scopes for example don't always get automatically completed.
