P.S. I don't have an Android device to test on. And to do so would mean installing a copy of the OS on VirtualBox etc. - would take me lots of time. Thus if the iOS version is ok, then possibly there is a bug in the Android version - so worth checking the core 'Weekly' format for the same issue.
But this would be separate to the theme issue with Andriod: https://github.com/gjb2048/moodle-theme_essential/issues/465 which is a browser thing - possibly.
