Same thing happened to us, today (end of tax year) we received a letter from HRMC saying our (backdated) claim has been refused because 'old MATCF form was used'. However we used the form dated 10/23 provided by the HMRC marriage allowance webpages - no other, more current form is available. Either they have not updated the date on the form (and its automaticaly rejected) or they have forgotten to link the new form with their webpages. I was eventually able to get through to an HMRC advisor today on 0300 200 3300 and the advisor has now accepted our claim and processed it. She promised she will let her manager know that the MATCF form available via HMRC webpages still says 10/23.
