Add this line before initialization
R89SDK.setLogLevel(LogLevels.DEBUG)
See all the logs in the android studio Logcat by typing in the Logcat search bar -> tag:R89SDK-
also if you find the logs very overwhelming and you just want the warnings and the errors you can use loglevel:ERROR
in the logcat search bar.
Logcat search bar has autocomplete so it should be really easy to find any other filters you might need.
