I already have a pro account but still can't use the 'branch protection' feature in the organization

This feature works normally with my private repo

anyone here ?

Hi @tbm98,

Thank you for being here!  A few of our features, including protected branches, are only available in public repositories for orgs on the free plan.

You can see a full breakdown of which features are public repository only here:
