Connectors versioning : 01 - Connectors in published apps
Verify that connectors have inner version handling with app versions. When an app is published, the connector that is used gets cloned and binded to that app version.
Running that specific app version will use the the connector version that was created for it.
App's development version will use the connector that is accessible from the UI.
You are logged in with a Workspace Owner or below and on the main Connectors page.
The connectorsReadOnly feature flag should be switched ON.
On /account/connectors-settings, the "Publish automatically, including for apps published to the shop floor" should be active.
