Hi,
Libreelec 9.2.6
Youtube addon just updated to 6.8.16 but had the same problem with the previous version as well.
Managed to set up API to access my account via the addon, so my Subscriptions list etc all load up, but when I try to play any video,
I get "Youtube Error - check the log for more information" and "playback failed - one or more items failed to play. check the log ....." messages.
Here is the log file: http://ix.io/3x9j
Thanks for any help.
