I was referring to this page to auto fill a field of an embedded form, which was working fine till a few days back but has stopped working since yesterday. Can you please help?
Is that an embedded HubSpot form? At a quick glance, it appears to be an external form. If you're using an external form and collecting the submissions using the Collected Forms tool, you wouldn't necessarily need to change the values according to the document above. Also, which field is supposed to be auto-filled? Nothing is autofilling for me, but that's probably because I haven't visited the page before.
