Adding Recurring Events to a Microsoft List in Calendar View

I think the one thing MS have not included in SharePoint modern (ie, a fully functioning SP Calendar, with overlays) is probably the one bit of functionality that everyone actually uses! Why do they do this?

Anyway, looks like Power Apps to the rescue... I have just been researching the same thing and if we create a custom PA form to our Calendar list, we could achieve at least the recurring bit (and I think all day event would be easy to add as well).

I haven't tried it yet, but here's the video link: (doesn't include monthly recurring but will get you started)
