You can't use this SDK with the latest React Native version as the Android version does not build anymore:
1: Task failed with an exception.
-----------
* What went wrong:
Execution failed for task ':react-native-phyllo-connect:compileDebugKotlin'.
> A failure occurred while executing org.jetbrains.kotlin.compilerRunner.GradleCompilerRunnerWithWorkers$GradleKotlinCompilerWorkAction
> Compilation error. See log for more details
React Native version: 0.76.2
New Architecture: NO
I assume it has something to do with the Kotlin version.
