So, according to the person I am emailing at Itch, everyone should be approving the bundle now. The listed revenue split will be fixed later. I hadn't put the call out because I was waiting for the revenue split listing to be changed.

Since it took a little longer to hear from Itch than expected, I'll bump the bundle dates back a little to be a month from next Friday instead of the Monday so everyone has time to approve.
