Collection works in Preview but not when actually running the App

Hi community,

I have a Gallery, which its data source is coming from a collection.

The collection contains data from several SharePoint sources. I have noticed that when I run the App in preview mode, the Gallery refreshes as it supposes to. However, if I actually run/play the app, the Gallery doesn't refresh - the Clear Collection and Re-collect data does not work.

Please advise, thank you.

Hmm, interesting formula. I haven't checked every aspect of it, but it seems okay.
Have you tried using the Monitor while you are running the app to see whats happening in the back ground when it fails?

Found the issue. There was another button in the cover page that requires the editing I have done for the refresh on the collection.
