The date format using Adobe Form doesn't get carried forward to Adobe Sign

Hi,

The date format using Adobe Form doesn't get carried forward to Adobe Sign. With the volume I am working with, it is just not possible to manually change dates in the form each time as there are several dates in the form and I have to send a large volume of the forms in one go. I tried using the script "Text1_es_:signr1:isdate(format=dd/mm/yyyy)" in Prepare form under Custom Calculation Field and it doesnt work. I tried locking the format and it doesnt work either. This is causing so much problem and we are considering to stop using this tool altogether. Is there another way to fix this or am I making an error in the script above?

Thank you.

BR,

Megs.

P.S.: I am using Acrobat Pro DC in Windows 10 Pro
