Does the plugin send out multiple reminders if the balance isn’t paid? I’ve started setting it up but can only see the one trigger, which means manual intervention is still required if they don’t pay it on the first try?
That is correct, there is no option to send our more than one notification in Notifier add-on so far. We will take your request into consideration though and in case there are more similar requests from other users we might include this option in one one of the plugin future updates.
