Type or namespace 'LTSeq' could not be found

After updating to 2.51, I'm getting this error:

Assets\Plugins\LeanTween.cs(1057,19): error CS0246: The type or namespace name 'LTSeq' could not be found (are you missing a using directive or an assembly reference?)

Unity 2020.3.26f1 on Windows 10 x64, building for Android.

This project has been dead since 2018. the developer does not respond here any more. You might want to switch to another tween tool.

Ok, thanks for the heads-up!
Odd though, the plugin has been updated in December: https://assetstore.unity.com/packages/tools/animation/leantween-3595#releases

Yes, apparently he just updated to fix issues with Unity 2021.. so there's a hope!
