File upload no longer working for multistep form

Hi all,

I have a site which was recently converted from trial to production type.

My site contains two multistep forms, both of which have attachments enabled for the second step. This uploads data to a Dataverse table which has a relationship with the 'Note' Dataverse table.

I can see that attempting to upload a file does create a record in the 'Note' table, however it doesn't contain any of the file details such as file name, size, mime type etc.
