Currently, when setting up a monthly recurrence, it's not possible to select days 29, 30 and 31 (please see the attached picture). This doesn't make any sense, and this doesn't happen in other similar tools. The expected behavior when for example a user configures a recurrence to happen "every month on the day 31" is the recurrence to happen on the day 31 (when that day exists on the month) and to happen on the last day of the month (when the month has less than 31 days).
