Tried to use the MdcTheme in our app but getting an “_Cannot create Typeface from ResourceFont(resId=17040217, weight=FontWeight(weight=400), style=Normal)”_ exception. Anyone experienced that before?

Are you using downloadable fonts?

nope

Please report the issue on the GitHub repo: https://github.com/material-components/material-components-android-compose-theme-adapter Any additional details (which font, sample usage, etc.) and even a link to a minimal sample project would help. Thanks 🙂
