We are making a change to the chat:read scope, which may impact some third-party developer applications. If your application is experiencing issues, please review the Chat and PubSub scopes list and refer to the Authentication documentation regarding OAuth or OIDC tokens to ensure you are using the proper scopes.

The current message is quite vague and requires us to review multiple other documents to try and figure out what changed…

Were you planning to publish this before or after applications will experience issues? How long should I wait before the cause of the issue is disclosed?
