Betterment Not Connecting to Simplifi (Care code: request-body-field-unsupported)

Hello @Phogramity,

Thank you for reaching out! In this case, I would see if the following steps work to resolve the issue:

• Make all of the accounts with the bank manual by following the steps here.
• Once you see the account(s) listed in the Manual Accounts section under Settings > Accounts, go back through the Add Account flow to reconnect to the bank.
• If the connection is successful, carefully link the account(s) found to your existing Quicken Simplifi account(s) by following the steps here.

I can also see that before this current error, you were receiving an FDP-103 error. If you do receive that error again once you go through the steps above, we do have an alert you can follow for this known issue:

Hello @Phogramity,

Thank you for your response! The alert I shared was just in case you ran into the FDP-103 error again after following the steps above.

I also noticed only one recent connection attempt from our side for Betterment for you as of this morning. To help us troubleshoot, please try the steps I mentioned earlier. After completing those steps, let us know how it goes, so we can troubleshoot further if needed.
