Edit: My mistake. I thought I had this issue too but I worked it out.
That is not how it appears to be working for me, though. For example selection > 0 and < 2 shows the group field when ANY 1 term is selected. Selection > 2 and < 4 shows the group field when ANY 3 terms are selected. Etc…
Hi, I don’t see “value is greater/less than” when I nominate a taxonomy field in the conditional logic. Only “selection is greater/less than”, which I had tried, and seemed to refer to the number of options selected rather than the value.
