@YouTube dear YouTube,
I've completed 1000 subscribers on my channel and now I'm waiting for the community tab on my channel please work on my request and provide me my community tab.
Thanks for reaching out. It can take up to 1 week to see the Community tab after passing 1k subs. Otherwise, if you have more than one Community Guideline strike on your channel then you won’t be able to use the feature. Let us know if this helps.
