Having issues filing company accts via Pro Tax in QBO? Not allowed more than one attachment- either the CT600 OR YE accounts. Both are required by HMRC. No help from QB

Hello Ktmbk2021-gmail-, we have recently introduced Workpapers in QuickBooks accountant, more information can be found on that here 

We do see that you wish to file more than one thing. Currently you can file the CT600, in the pro tax feature. This is a new feature we welcome all feedback, so we can make that feature the best for our users. 

Can you tell me if the above has been resolved? I have managed to complete my ProTax return for my firms annual accounts. When I E File and select HMRC it opens a summary page with basic numbers on the left and summary figures for trading Profit and Corp Tax due at the top (Not submitted). When I then click Transmit it asks for my credentials and then tries to upload the reports. Sometimes it does but I then cant click next as its greyed out??? when I try other times it doesn’t upload the accounts CT600 and says there is an error and to contact primary admin (thats who I am and logged in as!!!)
