TLS version
The PCI Security Standards Council has specified TLS 1.2 to be the new baseline standard for encrypted communications. Backend communication with the Android library now is supported with TLS 1.2 only. We encourage scheduling the upgrade of your Android devices to Android OS version 5.0 or higher and app version 1.19 or higher.
