> This is by designed. When you tag old commit and push to repository, github will check if event trigger exists on the workflow yaml “AT THE COMMIT”, while not the latest workflow yaml file. > > You can checkout the files based on `the old commit`, if there’s already tag trigger(on: push: tags) on the workflow yaml, tag on this commit, the workflow will be triggered. If no tag trigger, workflow will not be triggered. Reference: https://github.community/t/how-to-trigger-action-for-tag-on-old-commit/122341
