I have installed git-lfs, but the placenote.framework file is just 8Kb

After following the Unity install instructions through GitHub, the placenote.framework file is still super tiny.

Sometimes Git-lfs still gives us a hard time when cloning the repo. You could instead download the unity package file to guarantee that you have a seamless experience.

Otherwise, if you still want to use git, you could still download that unity package file and copy the placenote.framework file from Assets/Placenote/Plugins/iOS and replace the file in your git project
