**Your software**  
My Mautic version is: 4.x  
My PHP version is: 8.0 + 7.4

**Your problem**  
My problem is:  
when trying to add pre-populated contactfield details inside a landing page, it just renders {contactfield=firstname}

so when we have [https://mymautic.com/?email={contactfield=email}](https://mymautic.com/?email=%7Bcontactfield=email%7D), it does not render any details of the user.

Anyone know if maybe I am not adding this correctly or have experienced the same behaviour.

Maybe I am wrong but I do not think that landing page goes through same token replacment process as email.

It feels like this would be really slow for every page visit. You can use this technique for form population but not for LP (at least core mautic does not) and even then field hast to be marked as publicly updateable.

yeah, the workaround is to use dynamic content slot

Hi, this was never a feature.  
The ‘token replacement’ process is different for LP, since there is no script, that generates these values.
