Installing the superpatch did nothing for me either. I'm still getting "login temporarily unavailable" when trying to import Schwab data.
As Dovster said, "This is inexcusable. If TT is at all interested in having Schwab account holders purchase software in the future, it should send each of us a certificate giving us the 2022 programs for free. That way, if it does not work next year, we will not again waste our money ..."
