Thanks for reaching out. Once your channel becomes eligible, you’ll be notified in the YouTube app. However, it may take up to 4 weeks for Stories to show up after reaching 10k subscribers. Also, channels that have more than 2 strikes will not receive access to Stories.
Thanks for the confirming. As a next step, we'd recommend sending a feedback report directly from your YouTube account with these steps: https://yt.be/help/FQA4 . While you may not get a direct response, we do review and use the details to investigate and fix issues.
