I moved months ago from Kodi on OSMC to Kodi on LibreElec (always on Raspberry Pi3) because of much much much better stability with Kodi 18.x.
I use the system only for music (about 9.000 releases).
But now on Yatse if I download the album and artist previews from Setup -> Media -> Cache Management, it all goes fine without errors, but if I go out of my home wifi (for example if I want to see some albums of my collection outside at the bar with a friend of mine), i.e. without connection to the LibreElec home system, I cannot see anything of the collection, while I was able to see everything (albums and artists photos, artists stories) when I was on OSMC system.
What is the problem?
Isn’t the download to Yatse really supported by LibreElec?
Thanks in advance and kind regards
