Yes, but you need to install a build that is Kodi 18 Leia compatible. Installing a Kodi build that was made for Kodi 19 won't work (but a Kodi 18 build might not work for Kodi 19 either!). Keep an eye out for updates to your favorite builds – the teams behind them may be currently updating the Kodi 18-only builds to be Kodi 19 compatible.
