Classic form prefill not populating a simple text field
Trying to prefill a classic Airtable form via ?prefill_FieldName=Value. Field name matches exactly, but the value never populates. Tested with a single Text field, signed in as owner, no filters on the field.
This is for a form built in the Forms tab on the website, so it's not an "interface" form as far as I can tell (not sure what that is).
