Salesforce connector authorizations invalidated on October 3 - small subset of account across the platform

Between 00:31 and 05:25 UTC on October 3 (8:31 PM to 1:25 AM ET), Salesforce rejected a set of token refresh requests from FormAssembly. As a result, Salesforce authorizations for a subset of customers across all regions were marked invalid in FormAssembly. Connectors and dynamic picklists that depend on those authorizations have been failing since then with "Error connecting to Salesforce" or "Authorization is no longer valid."

Scope is currently being evaluated. Each identified account will be proactively identified. This affected a very small subset of accounts across the platform.

If your Salesforce connectors are failing and you need them working now:

Go to Preferences, then External Authorizations, and select Reauthorize on the affected Salesforce authorization. Reauthorize once per Salesforce user, from this page, rather than from each individual connector. Salesforce allows five active authorizations per user per app, and reconnecting form by form can exhaust that limit and break working connections.
Form responses submitted while the connector was failing were saved in FormAssembly and were not lost. Once the authorization is restored, reprocess them from the connector log.

If you have reauthorized since October 3 and your connectors are working, no further action is needed.
