I have re-released LibreELEC and I already have version 18.104.22.168.
You wrote that there is only version 22.214.171.124 in the repository.
As I installed LibreELEC 9.0.1 freshly, I had two versions to choose from:
I chose of course 2.3.15 and it is already good.
Just why, since you wrote that there is one version 2.3.15 in the repository, I could choose between 2.3.13 and 2.3.15?
