Recurring donations processed via RE7 can be reactivated, but RENXT recurring gifts do not offer this functionality.
We've had a few recent donors who requested cancellations but then changed their minds after the recurring gift was terminated via RENXT. While a few of the donors did end up providing their details again allowing us to create a new recurring gift, we lost one donor who said it was too much of a hassle.
for goodness sake please add the ability to re-activate recurring gifts?
