Hi Joanne,
I looked but have to admit I haven’t used this tool yet. I note the following:

The Geni World Family Tree is a unique collaborative, largely public collection of connected family trees. The path to user tool calculates the shortest path between two geni profiles in a readable format.
Please note that the Path-to-User tool may be limited by privacy settings or by anomalies in the Geni database.

Disclaimer: HistoryLink uses the Geni API but is not endorsed, operated, or sponsored by Geni.

I would suggest:
1. Take a look at your privacy settings to insure tat you are not blocking 3rd party app, and
2. When attempting to use “Allow” access by clicking te appropriate button

I’ve escalated your issue so that other curators might respond
