I've a GearVR app just approved for Oculus Keys, and it was created and firstly submitted as a free one. Now I would to submit an update, changing it to priced, but it seems I can't change this detail, because the corresponding radio buttons in Submission Info/Pricing section doesn't work anymore, so the "free" option cannot be switched to "priced".
If you are using Oculus Keys, then the price does not apply as your app is not being sold through the Oculus Store. You can sell the game yourself, for example on your website, and charge whatever you like for a Key. Thanks.
Thank you for your answer cybereality, now I got the point. By the way, once an app is approved "keys only" is it possibile to put an update in review for the Oculus Store again?
