This is a very minor thing I noticed earlier when cloning a Notification child app, and doesn't affect the function of the app in any way.
If I updated the name for a cloned app during the cloning process, the name did not initially display in the Apps List, the old name was shown. In the screenshot below, I cloned the first child App and gave it a different name, along with swapping one of the devices involved. When I was taken back to the Apps page, both the child apps display with the same name.
When I open the second App I see the name I provided when I cloned the App.
Clicking done and returning to the Apps page shows the correct name.
Instead of opening the child App, if I simply refresh the Apps page, including a hard(?) refresh using Ctrl+F5, the duplicate names are still displayed, it appears I needed to open the app and click Done.
