No notifications from LimeSurvey since LimeSurvey 2.72.2 (November 10)

See #{issue_id}#note_{comment_id}: I got a notification for 2.72.2 on October 30 and 2.72.3 on November 10.

I never got a notification for 2.72.4 which, according to the release notes was released on November 10. Note that the commit for 2.72.3 on the release notes dates from December 22 (8f5846c8d3) which is weird…

Since then there has been numerous releases, some including security issues and I got no notification at all.

Making this as part of #14540 (closed) since it has been broken since #14828 (closed).

Parent Task: #14540 (closed)
