All my options for adons are gon and all settings for KODi i must place new. A Backup what i have make don’t work for Profil , only if i make a Second Profil and i go then back to Master Profil then it Works longer. Ho know this Problem and Ho can tell me how i can repair it? A hard Reset don’t bring a better way, the same problem.
