Hey Nicolò,
You can use the [%BeginOfCurrentDay%] token instead of [%CurrentDateTime%].
It should work fine in your case.
Hi,
The validation which has been thrown in the microflow right technically.
$Reservation/ReservationDate = 30/06/2023
Current date and time = 30/07/2023
$Reservation/ReservationDate is not empty, which is true in your workflow.
$Reservation/ReservationDate is not greater than or equal to [%CurrentDateTime%].
30/06/2023 is not greater than or equal to 30/07/2023, which is false. Therefore, the microflow returns false in your validation.
