Filled in the form yesterday (using link sent out by Skywise). It wouldn't allow submission, so I saved the file as instructed, then reopened in Adobe - then had to fill it all in again! But then it would submit, and immediately got the reply back asking for ID and invoice scans, which were sent immediately. Hopefully, I'm in the queue and they haven't lost my application or are changing what they need!
Not that I'm desperate for the £600 or anything
