I have posts scheduled to repeat monthly. After setting everything up, I checked my calendar, and for months that have less than 31 days, the extra posts (29/30/31) are instead scheduled to all go live on the last day of the month. This isn't ideal as I don't want to spam my followers. If a repeating post is scheduled to repeat on a day that doesn't exist (eg the 31st) I'm happy for it to be discarded - how do I set this up? Thanks
