**What's Happening**
Starting at approximately 09:42 CET on August 6, 2026, users have been unable to authenticate or reconnect Salesforce accounts. This issue is affecting multiple versions of the Salesforce integration.
**What We're Doing**
Our engineering team has identified a recent code change as the likely cause and we are actively working to restore functionality and will provide updates as soon as we have more information.
