I am maintaining two versions of the app for development and production, and I followed steps in this how-to to clone the dev app.
The issue is that I am unable to change the app name. The production app’s name keeps reverting to the dev app’s name. It is just a matter of time before I change something in production assuming I am working in the dev app. 
Please let me know if this issue is not simulatable.
That’s the same behavior I see. The name of the app is stored in the anvil.yaml file that you’re pushing from Dev to Prod, and that seems to trigger the reversion on Prod.
Aah, that makes sense. So there are two app names, one that is in anvil.yaml and another that is visible in the app listing?
Displaying the name from the app listing area as the browser tab’s title should help distinguish between the apps.
