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.
Previously, I have been able to upload files which creates a row in the 'Note' Dataverse table which contains the files content in Base64 format. This looked as so:

The above picture is still how this appears in the design studio preview, however, in the actual website the attachments option has changed to look like:

I cannot upload a file using this functionality, even though the file meets all the file upload restrictions specified in power pages management. I get the following error:

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.

Please help!! We we're just about to go live with our site and are now stuck on this!
