In the unfortunate situation where you need to revert an app from "Fluent" mode, as is used in the latest versions of ServiceNow Studio and IDE, here is how to do it. This will cause the development environments to stop syncing and building using the SDK.
- Open the list of records in sys_app (open the left hand nav filter and type in sys_app.list)
- Use the Personalize List feature (the little gear icon near the top right) and add Package JSON.
- Double click in a blank area of that cell and clear it out, then click the check to save.
The application will now return to behaving like a traditional application and no longer sync and build using the now-sdk.
