All fixed.  The problem was a code block was sitting in front of the form submit button. I simply sent the code block to behind the form block and it is working just fine now. 

Such a simple fix but I was thoroughly bamboozled.

Hopefully this helps anyone else who finds themselves in the same pickle.

Thanks to the Squarespace help team member for telling me how to fix this. 

I have one form on my website where the form submit button is not working on mobile only (working fine on desktop; and other forms on the site are working correctly on both desktop and mobile).

I removed all design coding to check whether this was a coding issue, but it still would not work even with all custom code removed.

The button is simply not 'clickable' on mobile, ie, when hovering over it there is no option to click.

Is anyone else experiencing this issue, and are there any suggestions on how to fix this?
