content only shows if user_registered meta is less than acf date field

Hi, I’ve got a members area using memberpress and i’m using elementor and have dynamic conditions installed.

I’m trying to set it up so that a section on a page only shows if the registration date of the member is older than an acf date field.

I’ve got the acf date field added to a custom post type called content issues. And the relative date is entered for each of the issues.

so the dynamic condition I’ve put is:

dynamic tag: ACF Field (content issues date)

Show when condition is met:

greater than

(compare type) Text

(conditional value) user_registered

This doesn’t work. I’ve tried various combinations of show and hide and greater than or less than, and they either hide all or show all, despite the fact it should hide and show some not all.

MemberPress told me that their member register date is the same as the user meta: user_registered

any ideas if this is possible or not?

thanks for your help,
Matt
