Hi Lucas! This issue has been opened before the official release of the Kotlin Multiplatform plugin but we were already working with the plugin internally, so it is still valid. I'm not very familiar with the interaction between the Amper IDE plugin and the KMP plugin, but I believe some features require special handling for each build system, hence why we have this issue open for tracking. In short, it might be expected that it doesn't work out of the box for Amper, and we'll definitely look into it 😉
