Sonar scanning whole code instead of changes

Recently SonarCloud started to misbehave.
The scan should check only the new code but is instead checking everything.
Also looks like the rules have got stricter and our builds fail even for minor issues.
DevOps insist nobody has changed the configuration and the history confirms that.

The problem started on 30 November 2018


Sorry to get back to you so late, it seems we overlooked this thread.

Is this still an issue today?

Please let us know, thanks!
