What is the latest FX Software Version for new FX Radar Chrono?

I am trying to download the latest version of software for the FX Radar Chronograph for an iPhone 10.

In some other recent posts Centercut has version 1.1.25 and another member has 1.1.38. There was a recommendation made from the member who had the 1.1.38 version to de-install the FX Radar ( in my case I had version 1.1.25) and then download latest version using the iPhone Apps store. I just did that and the latest version I am getting is 1.1.25.

Q. How/where to get the latest version of software? Q2. Does anyone know what is the latest and correct version of FX software?

Thanks, Tom
