I just created a extension today, and I was following all the steps and one of them says I should complete " Extensions monetization onboarding.", however when I click the link, it just jumps to the extension page, there is no " Continue to Onboarding " link for me to complete this step.
I wondered if it takes some time to come up, or I am doing something wrong.
Just an FYI. This is still an issue as of today. The LEARN MORE button in the Extension Capabilities page still takes you to the main Extensions page instead of something more helpful. Fortunately I found this thread in a Google Search.
I believe I replied to your original post, but we had identified a small bug that impacts newly onboarded developers who were already a partner or affiliate on Twitch. Thank you for your patience! This should be resolved shortly.
