If there is a certain customer that you don’t want to be nudged then you simply have to navigate to the Customers page in the rePete app admin and search for the customer. If your customer was identified as someone to nudge, then you can simply find the customer and in the top right corner choose to Pause all nudges for this customer.
If you cannot find the customer within rePete then this customer does not have a predicted schedule and will not be nudged.
