Hi @Ryan_M ,

I'm in the same boat here. I have a return open which is currently dated 1/4/22 - 30/6/22 but despite changing the vat settings today, from quarterly to monthly, the dates have remained the same. I want to submit a return on 31st may but currently I get the warning message "Select an end date which is not in the future.".

Can this take some time to update or should it have happened immediately? 

thanks.

Steve.
