I am using Qlik Sense Desktop, not cloud. I created an app and just loaded 2 data files. My colleague added sheets. I got a copy of the app with the sheets and want to update the data files. when I select update I get an error - Data could not load to data manager. Please verify that all sources connected to the app are working and try adding the data again. Will someone please let me know how to verify that all sources connected to the app are working?
