This is an odd one, I'm trying to determine if the problem is with Schwab or Quicken. I'm running Quicken for Windows and had 6 accounts move from TD Ameritrade to Schwab. I removed the old Ameritrade accounts and then went through the steps to add them as new accounts via the online setup process with Schwab. Initially, all 6 accounts showed up, and I was able to create new accounts in Quicken and link them. Today, I got an error saying one of the accounts doesn't exist at Schwab. So I went through the process of adding it, but this account doesn't show up on the list of accounts Quicken presents to me from the Schwab setup. I've double checked and Quicken is granted permission to the account in my Schwab profile. Looking for information to troubleshoot whether this issue is on the Schwab side or Quicken side.
