Error trying to run the demo

[Minus274]

When trying to run the demo in Unity Version 2018.3. I get lots of errors like the ones below.

Assets\UtyMap.Unity\Geocoding\UtyMapGeocoder.cs(41,38): error CS0104: 'IObserver<>' is an ambiguous reference between 'UtyRx.IObserver' and 'System.IObserver'

I tried changing IObserver to UtyRx.IObserver, but unfortunately that didn't work.

Any ideas on how to fix?

To be honest, my expectation that using UtyRx.IObserver explicitly should fix it
