Hello,
I haven't tested this on Android, but at least on iOS, if you use your example project, click on "Disable", and then click "Is SDK Enabled?", it shows that the SDK is still enabled. It may be disabled but the function isEnabled returns like it is enabled.
It is problematic because if you call Adjust.getAttribution, it will never call the callback in that state.
This was not the case before v5.
Thank you
Louis
