Based on the knowledge sources, I don't see specific information about linked properties not updating when replacing a lookup table with a new CSV. The documentation describes how to replace lookup tables via the UI, API, or Warehouse Connectors, but doesn't mention troubleshooting for when the linked properties don't update after replacement.When you replace a lookup table, the system should automatically join the new data with your events or user profiles that contain the mapped property. The documentation states that "The benefit is that you don't need to change your tracking code at all. You can upload this Lookup Table after the fact and it automatically joins onto all prior events or user profiles with the mapped property." Lookup Tables: Enrich ingested data using a CSVA few things to check: 1. Make sure your new CSV follows the same format requirements as the original, with the join key in the first column 2. Verify that the header names in your new CSV match what you expect to see in Mixpanel 3. Confirm that your CSV meets the validation requirements mentioned in the API documentationIf you're still experiencing issues after checking these items, I would recommend contacting Mixpanel Support as mentioned in their documentation: "If you have any questions or encounter any issues along the way, do reach out to our Mixpanel Support team for assistance."
