I was part of the beta program through Google play. I opened Kodi to find that it had updated to v19 on my tablet. I left the beta program, uninstalled the app and went to install the public stable 18.9. Unfortunately, when I open kodi up, it reverts to v19. I have attempted to clear data and cache on both the kodi application and Google play app. I also tried to sideload the apks from the main kodi website. I keep receiving "app did not install." Help would be greatly appreciated. 

My android version is 10.0
