I spoke with 5 different agents today, Joy > Alli > Angelo > Dess and eventually Lead Ariana.
I was told that there is no resolution to this issue.
We tested network connectivity using traceroutes in both direction and by connecting to POL and the game from my brothers account to illustrate that the network environment and device can connect to POL and to the game nd the support team confirmed that regardless of receiving an POL-0206 network error, that there was no indication of network configuration issue.
We also confirmed that the account registration appears to be correct and there were no steps missing in creating the POLID, etc.
The only recommendation I received from support was to try purchasing a subscription to the game to see if that would resolve the network issue. This does not make much sense to me as the issue existed while an active subscription was applied to the account, and that the error code received was not an error code associated with account access or subscription, but one specifically with network connectivitiy issues.
When asked what the future steps would be should I subscribe and it does not magically resolve the issue, I was told I could:
1) wait a few days (in excess of the ~342 days since initial issue was reported)
2) Conduct Network Tests (repeat the same network tests we had done moments prior for some reason)
When asked if there were any further escallations we could make or tests we could run I was told that there was absolutely nothing else to do except repeat the same canned responses for eternity.
If anyone else has experienced this issue or something similar, or if there is an official moderator or representative from the dev team that could perhaps provide insight as to why my copy of the game, which I paid for, cannot access the game servers, I would greatly appreciate it some additional support in finding a solution.
