I need to add a date input field to my contact site, so that users can select a date when we can call them back. I filled the attribute min
with the date of today, to prohibit the user from selecting a date from the past.
But if I try to submit I get "Please enter a value greater than or equal to NaN."
I figured out that this is a bug in the old jquery version which magento 2 is using. They are still using jQuery 1 even when there is already jQuery 3.
What is the best way to replace the jQuery version for the contact site?
