Hi there, it can take up to one week to see the Community tab after passing 1k subs. Also, channels that have more than one Community Guidelines strike aren't eligible for this feature. Hope this helps.
Thanks for reaching out. Make sure you enable custom layout for the community tab to be visible. If you still don't see it, file a feedback report: https://yt.be/help/a4gp . While you may not receive a direct response, we do review everything to investigate and fix issues.
