Triggering id and i variable are not accessible for button action event in a collection. It just returns undefined.
On a side note, has anyone experienced a really slow mobile editor once adding more than a few screens? The app I made works fine but edits take forever...
When triggering it through a control query event i can get triggering id but not index (which I need to be able to access the information of the card which the button was pressed). See screenshots:
