First, thank you for your immediate answer...
I am referring to all the available adds on... I just installed it, so there are enough updates to be installed!!!
Wait for network before starting Kodi option, is enabled....
Have also to mention (if it affects the whole procedure), that the time that appears on my Kodi screen is totally wrong (even after I entered on the field of Timeserver #1: pool.ntp.org, and Timeserver #2): gr.pool.ntp.org...
