As you predicted, it of course became the required only option for creating invoices.  Yet 7 months after your post when they made the forced permanent change, and now another 2 months after that, they still have not resolved this issue.  Sending feedback never seems to actually do anything since they just keep rolling out half-baked replacements for stuff that had been working fine before that, and taking years to add back the missing functionality if they ever even do at all.  If QuickBooks wants to revamp a feature, they need to make sure it does AT LEAST everything the existing feature is able to do before forcing it upon their customers, and ideally more than that so the customers actually look forward to the changes instead of fearing them.  Yet I think every one of their forced changes that I've experienced has actually removed functionality.
