Compose calendar event URLs do not open the compose dialog on mobile

So taking the following link: https://outlook.cloud.microsoft/owa?path=calendar/action/compose&rru=addevent&subject=test&body=test

On mobile devices it will open outlook and the the compose dialog will not open.

We used to use the deeplink url but had to switch to the above as it has a bug where it ends with a blank screen as described here: https://techcommunity.microsoft.com/t5/microsoft-365/outlook-deeplink-calendar-compose-ends-with-a-blank-screen-on/m-p/4212741#M53563 

I've seen threads on both of these bugs since early 2023 with no resolution, Is there a better place to raise it?
