Does config input need to be re-inputted when you update an app?

Hello - we have a Private Team app which reads data from an API which is specific to the owner of the Tidbyt and so we provide them with a key that they can put into the config in the Tidbyt app in order to provide the information from the API specific to them?

Does anyone know if when you push an update to the app, the config information needs to be reinputted by the user after the update (assuming the config stays exactly the same when the update is sent)?

I’ve published updates to my apps, and config settings that haven’t changed keep their values. People won’t have to reinput those settings.
