Where and how do I report programming errors that appear within FamilySearch?
Under Suggest an Idea here in Community. Or if about the new person pages report them in the New Person Page group: https://community.familysearch.org/en/group/316-new-person-page You do have to join the group to post there.
Actually, report errors (bugs) here in General Questions. Suggest an Idea is for new Ideas or concepts. Alternatively, if the page has a Feedback link somewhere on the side, you can report the error there as well. Two different paths to reporting, but it all gets back to the specific departments working on FamilySearch.
