I'm successfully connected to Ally Bank, and one-step updates are working. But when I try to add a new account and select Ally Bank, I'm prompted to enter my username and password, and I keep getting a "CC-503" error saying the bank isn't accepting them. I've verified multiple times that these are the exact username and password that work to log in to the bank on the website, yet the same credentials won't work to add a new Ally account in Quicken.
I'm having the same issue with other banks too. The option to add a new account and link it to the bank isn't working.
Please advise!
