java.lang.UnsatisfiedLinkError when migrating to androidx

Hello,

I have an app using scichart 2.1 that runs well. I am trying to migrate to use androidx libraries and am now encountering a crash when runnign setRuntimeLicenseKey(), as shown by the trace below. Any idea how to go about resolving this? Is this something that would be solved by upgrading my SciChart version?

I have minSdkVersion 23, targetSdkVersion 28

Thanks
