Hello, I do have trouble getting it to work with Unity 2020.3.20f1.
I did set the Scale to fit to true but it does not seem to work after the upload on itch (currently still a draft, so I can't provide a link).
Hey there, I tested on 2020.3.23f1, and it seems to be working as expected. Are you sure you used the correct version of the package (v2.2)?
