Hi – same here, I almost got it working with a nested XML. I could populate the repeater field… but if the record had too many entries the whole process would time out. Also, the client would need to convert their CSV to XML first, which would be beyond them. So I’ve reverted to using CSV and have restructured my posts so that the repeater field isn’t required – using another custom post type for the repeater data instead, grouping together with taxonomies & linking to them with ACF select taxonomy. Its not ideal but it does the job.
