Error when submitting iFrame embedded Formie form on iOS devices
Describe the bug
Hello,
I have a Formie form that is embedded on a website via iFrame. I have updated the frameAncestors accordingly and the embedded form is submitting without issue on my desktop device (macbook).
When I try submit the embedded form on a iOS device (iPhone), it is erroring with the below response:
{ "name": "Bad Request", "message": "Unable to verify your data submission.", "code": 0, "error": "Unable to verify your data submission.", "status": 400 }
Full response for request in network tab:
