Microsoft Forms now available in PowerPoint

This is the feedback I've had from by ticket, it's not good news I'm afraid 😞

If the option "Let users access the Office store" is switched off it is by design to get the "Office 365 has been configured to prevent individual acquisition and execution of Office Store Add-ins" notification and not be able to use the Forms feature in PPT (Please see the Note in the "Insert an existing form or quiz" section here: https://support.microsoft.com/en-ie/office/insert-a-form-or-quiz-into-powerpoint-1a316f81-9ea7-4bc2-bda0-024c0d780df1?ui=en-us&rs=en-ie&ad=ie; 

Support has already raised a design change request to the Product group, asking for the Forms feature in PPT to work despite Let users access the Office store being switched off; it was rejected with the following justification: 

"Thank you for contacting Microsoft regarding your recent PowerPoint design change Request about being able to add Forms without turning on the organization to the Office Store. We have investigated this issue and determined that we must reject this request.
The current behavior is not a regression, and the root cause is related to the way the Forms is integrated in PowerPoint to allow for users to be able to sign in automatically using the Office credentials. While we are looking to continually improve the experience the potential change is not trivial. After much consideration, we feel that this is not a change appropriate for a sustained engineering release. As we improve the platform over the next few releases we will keep this feedback in mind and improve the current experience.
Thank you for bringing this issue to our attention and continuing to work with us on improving our products for customers worldwide. Again, we apologize for the inconvenience."

I'll push for fix via other channels but it's looking like we will not be able to use this functionality while we manage Office 365 add-ins 😞
