I cannot, unfortunately, confirm this assessment.
In the manual linked by you it says:
In development
The tool is still in development. As for now the preview is only available to paying members. The final tool is likely to be available to free users as well, though the functionality will most likely be quite limited. Virtual GPS is a paid feature for example, but there most likely will be other limitations as well.
And, indeed, if I open the link (as a normal member) all I get is an explanation what the limitations for normal members are (which are fine), some ads (which is also fine) and another box saying that you also need to be a paying member of geocaching.com (which, as already mentioned in another thread, does not really seem to make sense, as there does not seem to be any more PMO-related stuff involved in the tool than in other functionalities on PGC).
And that’s where it stops for normal members. Thus, for the time being, no functionality at all. Therefore, all we can hope for at this moment, is that indeed at some stage the development of the tool will progress and the limited functionality for normal members announced in the above cited text will be implemented.
