Thanks @David-TP 

The Internet Speed test is definitely available on V3 - see attached screenshot. I have kept the original packaging which confirms it's V3. Is it also possible to check the hardware version in the app as well or is it only available on the original packaging?

I'll have to buy an X20 V3 to test if it works with the X50-OUTDOOR unless there is another way to remotely test the internet speed?

It's an important feature when managing sites remotely that' would be valuable to other customers as well.
