As ever, Jackal provides a useful solution (or workaround, in this case).
To address your concerns about the time frame of this issue, I am in contact with Dick, who is investigating the technical side of this, on a regular basis. Last week there was a brief and hopeful period when the emails alerts arrived again, but then stopped. Testing is ongoing.
From what I have heard from Dick, this is a very difficult issue to diagnose, partly because the system seems to be set up correctly on our end, and recreating the issue has been intermittent.
I encourage you to try using MyFlyerTalk until we have this issue resolved, and thank you for being patient with us while this important functionality is offline.
Please continue to alert me via this thread if you see a change in your email alerts, so that I can pass the information on to Dick.
Thank you,
Paul
