I just moved from OpenElec to LibreElec.
When I was using OpenElec, and if the Guide was left idle, it would continue to scroll. I would turn the TV back on, and I would be able to view the current channel line up. However, LibreElec doesn't do that. If I turn the TV off, and then several hours later I turn it back on, the guide was right were I left it, several hours old. I have to exit out of the guide, and then come back in to get an updated guide.
I've reviewed the settings several times, and I don't see anything that I need to change to get the guide to scroll when its idle. Is there a setting that I can change, or something to tweak? Not that this is the worst thing in the world, just annoying.
