@simonwalsh Add "skipLibCheck": true to the "compilerOptions" section in the tsconfig.json for the plugin. This will disable typechecking node_modules, which seems to be the default for every React app I have worked on, so I think it is okay. Apparently it’s not set by default for capacitor plugins though.
