We really like the card format in forms. The UX is much better in most cases. However, we have some significant problems that keep us from being able to use it.
1. If the user accepts any autofill from the keyboard, the card becomes unresponsive, or you lose the ability to scroll to the bottom of a card, or you lose the arrows to go from one card to the next.
2. On Android (iPhone seems to be fine), the camera option never comes up, even when it's selected in the build stage. I can get to the gallery but not the camera.
I need to give over 2.5K individuals access to a form, and many are older, so any bugs are going to be very problematic. UX is critical in this situation.
