Hello Glenn
Thanks for reaching out to the Community.We are speaking with our Making Tax Digital senior support to see if we can get a log for you to pass onto them as proof that it has been accepted and submitted for the date range concerned. We have created a case and we will email you from it and continue this conversation further as we may need to get your VAT number and as this is a public chat we do not want that information in here for your own security.
Thanks
Emma
