Hate to bring back a zombie topic, but I am here with the same concerns. I have a setup where I am sharing some information externally - I already created a separate Page with the 2 tables of information in sync mode. But even though I have Shown the fields I CAN share, I cannot see how to disable that Expand Row button.
This is a big problem because I have sensitive information that can then be accessed through the “Show Hidden Columns”
Is this an option in the next tier? I am on Pro currently, and am not adverse to going up to Team if I HAVE to.
