I am getting same messages.

I have registered for MTD & had email all accepted by HMRC. The VAT return I am trying to file is for January to March so does this mean I do this one the old way & then then for all subsequent returns the new way? 

Spoke to QB advisor (I am using desktop btw)absolutely no help. Put VAT number on supplier account, made no difference. She said file the old way so I did that on QB but I ticked paper method (as I always have) & then went on to HMRC website to file the old way & I can't! There is no option. 

The advisor told me to call HMRC! which I did but they are too busy to take calls & so I have just submitted an enquiry form. 

QUICKBOOKS - PLEASE ADVISE ASAP!
