Hi David
A new version of Standard Accounts is currently being tested, and will be released as soon as it has been passed. This new version is fully MTD-compliant, so you should update to this version as soon as it's been released.
In the meantime, if you have already signed up for MTD with HMRC, you will not be able to submit your VAT return manually. If your VAT return was due yesterday, please contact HMRC to inform them that you're waiting for a software update. HMRC will not penalise you for being late.
Regards
Paul
