When I try to install SmartBeat in Unity, I get an error message "Undefined symbols for architecture arm64:" and I cannot build the project.

If you are using SmartBeat with Unity 2019.3 or later, the following error may occur during the build process with older versions of SmartBeat Unity SDK.

If you are using Unity 2019.3 or later, please use the latest version of SmartBeat Unity SDK (Version 1.21 or later).
