Don’t know what you are doing different, but mirroring a mirror column is just not supported. You can have two board showing a mirror to the same column on a third board however.
Hi @MaxLogic_Lisa , how are you? I understand you are trying to achieve that certain process flow using mirror column. Have you tried using the same item live on different boards instead? There is a newly launched app called Same Item Multiple Boards by Formula Lookout, let me know how it goes
A possible solution for mirroring columns can be using Lookup Sync app (available on monday.com Marketplace), which can handle syncing data between different columns on various boards. It also allows for multi-column mapping and keeps everything updated automatically. This might help streamline your process if mirroring isn’t working as expected.
