Comparing revisions

Given two commit hashes; how do I compare them and show the diff in the GitLab web interface?

When I type commit hashes into the “Compare” page (via left navbar) it always says “nothing to compare” and I kinda have to fight with the drop down.

Is there a way to do this?

Use this template to compare : https://gitlab.com/your-project/-/compare/from_hash...to_hash

Real world example : https://gitlab.com/the-automation-club/raspi-install/-/compare/b44bbde62c4630ceb17a58409bc58c7e62534256…3f9a9d674edb8af624b0f8571233789070c62abe
