The experience SDKs, specifically assurance and core, reference classes from the old Android support libraries and should use their AndroidX equivalent libraries instead.

Apps that use AndroidX rely on the Jetifier to transform Adobe's SDKs in order to consume them, and are unable to drop the build time expensive 'Jetifier' due to Adobe's SDKs.

Is there any plan to update the SDKs to use AndroidX and release a newer version of the libraries with it?
