I just released PackRat 1.1.1. This one fixes a problem brought to my attention by a user. PackRat wasn’t syncing past reminders. This turned out to be yet another problem with the Backpack API. I figured out a workaround and now you will get your past reminders.
This may help with recurring reminders as well. Due to another problem with the Backpack API (it doesn’t support recurring reminders), if you delete a recurring reminder in PackRat it is entirely deleted in Backpack. But now, you may be able to retrieve the reminder in the past reminders and reschedule it.
