Is anybody else having realm issues where your QBOA realm number is mis-matched with an old, closed desktop client?

This mis-match has popped up over the past 10 years and currently carries over to the ProConnect umbrella. It has prevented me from using Link or ProConnect Tax Online. Techs from QBOA, Link, ProSeries and PTO have all been contacted; the issue has been unresolved for the past 10 days despite daily, hour-long tech calls and emails.
