'Start Rollout to Production' button disabled

I had this problem and it is solved. There was a pending task to complete.

Put you mouse hover the one menu marked in "grey", you will see a tooltip showing you the point to correct. correct that point and that Menu will be marked in "green".

In order for you to deploy, all Important Menus must be marked in "green":

• App release
• Store Listing
• Content Rating
• Pricing and Distribution

Hope this will help

I had a grey triangle with an exclamation point to the right of "Store Listing" in the pane to the left. Hovering over it, it said "You need to add at least 2 non-Android TV screenshots." Uploaded another screenshot and now there is a green checkmark instead of the triangle, and the release button is enabled.

• App release
