Can't publish a world
I've been working on a CMI world. When I attempted to install a Kudos board it wasn't permitted. Updating the board resulted in a fail and a warning that something went wrong. SO, I redid everything in a legacy world. Fail due to unreleased content.
I did read about a similar issue, however this issue seems like cyclical failure. Nothing being used in this world is from anywhere but Meta.
Also, 'Publishing' is not an accepted label, FYI.
Perhaps I've been awake a little too long. Any help?
I would encourage you to learn to build your own IWP instead. This way you don't have to rely on something as generic as the Kudos board, which is basically just a tip board.
Here is a good guide to get you started: https://developers.meta.com/horizon-worlds/learn/documentation/mhcp-program/monetization/meta-horizon-worlds-inworld-purchase-guide
Also an article I wrote on the subject a few months back: https://developers.meta.com/horizon-worlds/learn/documentation/mhcp-program/community-tutorials/in-world-purchase-iwp-in-codeblocks
