In early 2022, the org I'm consulting for loaded all of their recurring donations into Salesforce, but since then the Last Donation Date (npe03__Last_Payment_Date__c) field has not updated. Both Next Donation Date and Effective Date are working.
Thanks, @Ajaypreet Singh Saini. If you or anyone you know can make sense of the Apex class, I found the source of the code for updating Next Payment Date, Last Payment Date, Paid Amount, and Number of Paid Installments.
