All my movies do not get the RT % rating.

Reinstalled and no fix. I have 2 HTPC's running LibreELEC (Leia) 9.0.0. One is Generic.x86_64 and the other RPi2.arm and both have the same problem. Rotten Tomatoes ratings worked fine on both HTPC's with the Krypton mod and my NFO files haven't changed.

May be an issue with your library. Can you try removing your movie library and add it again.

The .nfo's are fine.

For most members here the change from Kodi 17.6 Krypton with Aeon MQ7 Multi-Mud to Kodi 18 Leia Aeon MQ7 Leia Mod working fine.
But you are not the only one who has problems with the ratings when updated Kodi and Skin.
Member @wints  have the same problem, tried to helped, his .nfo's are fine, same problem but have also still no idea.

That it works for most is the only thing left is an exclusion procedure which is different for you than for us.

I personally suspect that something went wrong with the overinstall/upgrading of kodi or the skin. A complete reinstallation (new, not above - also all appdata stuff) may be the last option. If that does not help I have no idea ...

I once again looked at the ratings codes in the skin. They are ok.
The .nfo scraper and the .nfo spellings and handling in the kodi db have not changed in any way in Kodi 18.

Any other little thing in updating has been different for you than for us. We have to find out with trial and error ...
