The features and functions of the macOS version do not always equal what the Windows version offers. One example: in the Windows version, you can narrow the countries to test for the "Speed Test" but the macOS version does not have that capability. Further, when I asked ExpressedVPN support how to narrow the testing region, the support staff, apparently no knowing that the differences between the Windows and macOS versions, sent me a screen shot showing where that button was located and when I responded with the same screen shot of the macOS version, they insisted that I send it to them 3 times insisting that my screen shot was wrong. Finally, the support staff agreed that the function was not available on the macOS version using wording that indicated they were surprised (perhaps embarrassed) that the function was missing on the macOS version. When I asked about priority for the correction, the response was non-specific.
I use ExpressVPN; my comments here are a result of lack of quality assurance between versions of the product, lack of knowledge from the support staff, and lack of commitment to quickly fix the missing feature.
