Gitlab-ci.yaml in different project - trigger on change?

Hi,
my ci path (project A) is set to a file in another project (B).
When i push changes to the ci.yaml (in B), the pipeline (A) is not executed.
Shouldnt that work without the need for extra triggers?
If not, where would I trigger what?

Hi,

Please share your both projects’ .gitlab-ci.yml config for better clarity, and explain what are you exactly expecting.
