Describe the bug After updating to version 3.3.2 I have found, that my app starts crashing. Last working cio SKD version is 3.2.0. I suspect Gist dependency update as a root cause of the problem, as java.util.Base64 is available from Android 8. But cio declares support for Android 5 so this is why i consider it to be a bug.

To Reproduce Run your SDK on Android 5-7
