My TravelBank is still updating correctly though with my flights over the past 2 weeks. Are you having issues with that? I also have the error message it just doesn't seem to be impacting anything.
The problem is that
I can't contribute money, as explicitly stated in the apology message. I get some consultation fees as gift/credit cards, and just deposit them in the gift registry/travel bank. Haven't been able to do for weeks now, and would like to use em on some big airfares. No reply yet from GS btw.
