Indeed, looks like a bug with 3.9.2. Closing for the duplicate ^

I'm also receiving same error file not found for fonts.

[imhoffd]

@Barathwaja Those are the same resources as in the original issue. The fix is coming to @ionic/app-scripts soon. See #2675 (comment).

[mebibou]

@dwieeb actually no it is not the same issue, just realized this now. #2675 is talking about loading custom fonts, which now works, but I have the same problem as reported here which is that the default Roboto fonts are not included in the assets folder for Android, because they are supposed to be built-in. CF my issue on the app-scripts

I'm seeing similar behaviour. Default Roboto fonts are not loaded for production builds, only for dev builds.
