Hi Mark,
They are still working on a fix to accommodate for leap years since the schedule cron can’t be changed.
A possible work around is to have a Condition Control Flow in the flow and get the current date using a Calculator step and send it to the first condition if its is the 29th of February.
It is similar to what is being done is the below article but the first condition step will require a return statement for the 29th as well.
Please let us know if you have further questions.
Kind regards,
Navessa
