Form Scrolling down to show more tabs or options

Hi,

I have a couple of forms that are used by my customers on arrival.

I have a page dedicated to taking a photo.

Once users click on Take Picture and then take the picture the page doesnt scroll down or become obvious that they have to click submit to go onto the next page.

Some of my clients have just sat there thinking it was going to load.

I have just tried to do a screen shot for you.
I am working off a connected monitor but users use a tablet when filling it in.

Is there something you can suggest?

My form is

How about adding "Form calculation" widget to detect if "Take Photo" have an image? You can then show a message so they will know when to proceed.

Here's my demo form: https://form.jotform.com/92584620187968

Please check and let us know if that could work for you.
