@brandoFS For now I've added the SpongyCastle dependency to build.gradle //SpongeCastle compile('com.madgag.spongycastle:core:1.54.0.0') compile('com.madgag.spongycastle:prov:1.54.0.0') And added it in the MyApplication class static { Security.insertProviderAt(new org.spongycastle.jce.provider.BouncyCastleProvider(), 1); } It's not the solution...

@sallar I guess it's too late but... Maybe you can try with: ``` config: { fillFormatter: { min: 4.5, }, .... } ```
