Hi everyone. I have been trying to mirror some of my columns from one of my boards to another board. I want the native data from board A to be mirrored to board B in which the data is then used for other stuff. When I mirror the columns from board A to board B, the data randomly stops in in board B. Like there will be a cutoff where data that exists in board A (which is completely full of data) does not exist within board B past a certain point, despite the columns being mirrored. I am having trouble finding help on this, so nay help would be appreciated.
