Currently once submitted, the VAT reports cannot be changed. There should be an option to un-sumbit so there would be a possibility to edit mistakes (it was possible in the 2018 version of KashFlow).
I also miss this!
I can't see my 2018 VAT reports at all since the update. They seem lost...
Re: Lost 2018 reports
I assume you've clicked to change the year on the new VAT screen.
Theres a pull down year box, just above the 'Period' header - it will default to 2019
You won't be notified about changes to this idea.
