Does "write to other table" function not exist anymore?

Yes, the "write to table" feature still exists, but it's been updated. The legacy "Write to Other Table" columns are still available when you use the "Add Enrichment" button, while "Send table data" is our new way to send data between tables. The legacy option will remain available until the rollout of the new routing features is complete.
