ChatGPT Business Skills appear installed/enabled in UI but are not available at runtime

Additional note: we are now seeing what looks like the same class of issue with Company knowledge / connectors. In the UI, Slack is enabled for the chat under Company knowledge. However, in the actual chat runtime, Slack is not exposed as an available connector/tool, and the assistant reports that it cannot access Slack even though the UI shows it as enabled. This looks structurally similar to the Skills issue: the UI/backend state says a capability is enabled, but the runtime does not mount or expose the corresponding resource/tool. This may indicate a broader workspace-level propagation or enabled-state caching issue, not only an isolated Skills problem.
