Issues with Date Field when used on mobile device?

Hello,

I have been using JotForm for years and I love it. I created a form recently that has a date field, and users are having issues submitting the form.  I know it has to be a certain format (09-18-2018 instead of 9/18/18 for example), but even if it's in the correct format, we're still having issues.  It seems like the issues happen more often when using a table or mobile phone so it's a touch screen, not on a computer.  We have also had the issue when the person uses the calendar date picker, rather than typing it in.  Sometimes it works and sometimes it doesn't...I can't figure out what the issue is.  Do you have any advice on how to fix this issue?

You can enable Calendar Popup option in Date picker:

That should help you when date picker is used on mobile devices.

You can test my clone form: https://form.jotform.com/82606293983972

Please try and let us know how it worked.

Thank you!
