Quicken continuously asks for verification for the American Express bank account. I've attempted getting the code via SMS, email, and phone. Once in a while I'll actually get a code, usually via email, but it soon askes for another one. I usually don't even get the code via SMS or voice. I've repeated this effort up to 8 times using each method! I ended up just choosing to skip it and have removed it from OSU entirely. Not a very good solution.
Some have suggested using "American Express- Banking" which is what I have. I've also done all the usual steps (removed/restarted online setup), run validate and super validate, shut down/startup, etc.)
The issue has been ongoing since around the update before the last one.
