Xumo Add-on Remains Unavailable In Kodi Repository

A Kodi forum user reports that the Xumo streaming add-on appears in the Leia (v18) repository but is missing from Kodi 21.2 repositories on one Nvidia Shield device. Community contributors found the add-on still uses Python 2 and was not updated for Kodi 19+ (which requires Python 3), indicating the add-on is likely abandoned. Users should avoid installing outdated add-ons.
