We have occasional issues with values stored in cookies not being stored in hidden fields on form submit. Sometimes the information in the cookies are stored and sometime they are not.
Support is trying to help but I am wondering if anyone has any insight on how to trouble shoot.
1. We store utm values in cookies when people come to our site.
2. When the user converts via a Marketo LP we auto fill the hidden fields with values from set the cookies.
We have tested in multiple browsers (normal and incognito modes) and always the cookies are set but on submission the values are not always stored.
Thanks in advance,
