We're continuing to investigate the Salesforce Pardot connection errors and are working with Salesforce to identify the underlying cause.
Reconnecting your Pardot account in Zapier may resolve the errors. We've seen recovery for a small number of customers who reconnected, but we haven't confirmed that this works for everyone affected.
If you're still seeing errors after reconnecting, or you need help, please contact our support team.
Thank you for your patience, and we'll share another update as soon as we have more information.
