Adding a loading screen

Video Tutorial

The below video tutorial demonstrates how to add a loading screen while PDFs are being generated in your Bubble app (relevant section is from 38:05):

Instructions

If your users are creating large PDFs that take some time to create, you may wish to display a loading screen.

You can show an element directly after the 'Generate a PDF Creator' action is run. In this example, I'm using a floating group as a loading screen:

You can then use the 'When PDF Creator downloaded' action to hide the loading screen when the PDF has been successfully downloaded:

You can also hide the loading screen (which is FloatingGroup A in this example) using the 'When PDF Creator is saved to database' action.
