We are experimenting with Annual cycle in our company for some workloads we have to repeat every week, month, year etc...
So far we have tried:
Classic SharePoint Online Task list with Gantt (modern doesnt support Gantt)
Custom list in SharePoint Online (with some SPD and or Flow attached for the logic)
Anybody have any better suggestions we can try out inside the Microsoft umbrella? Only 2 stipulations
It has to be OOTB functionality so no extra coding of any kind
No 3rd party software
