You may have witnessed that, upon making some changes on your app, these will not show on the App Previewer. This article outlines why this occurs and how you can work around it.
The user has just made a change and the App Previewer still shows the previous state. For instance,
The root cause lies in the fact that the user has not saved the change (as you can see the Save button is active) and thus the Preview shows the latest saved version. That is, the preview only displays the changes after we hit the Save button. If we are making changes and we have the native preview on the right-hand side, this will be showing how the app used to look the last time it was saved.
To work around this, we suggest you click on the Save button whenever you wish your change to be reflected in the App Preview.
1. Navigate to Create -> Design or Build depending on the changes you wish to perform.
2. Perform the change you wish.
3. Click the Save Button
As soon as you click the Save Button, you will notice that the App Previewer will reload its content and show the same content exactly with the changes you just made.
