I note that it is now possible to download LibreOffice Portable 7.2.2.2 from LibreOffice's own site here: https://www.libreoffice.org/download/portable-versions/
However, it is not downloadable from PortableApps here: https://portableapps.com/apps/office/libreoffice_portable The version on offer there is still at 7.2.1.
Seems like someone not clicking a button somewhere.
