'No content available at the moment.' message when using the app to access moodle.org

As reported by Ralf Hilgenstock when using the new version of the Moodle app (3.7.1) to access moodle.org, a message is displayed 'No content available at the moment.'

Edited to add: This issue affects lang.moodle.org as well as moodle.org, and I guess when the Learn Moodle app is updated it will also affect learn.moodle.org.
