I'm new to QGIS.
I'm currently using the new version 3.20.0 Odense and I have some troubles setting up the rule-based labelling for a layer.
Essentially, what I need is to automatically swap labels base on active layers; I don't even know if it's possible but I have tried several conditional statements in conjunction with
is_layer_visible and everything seems to be pointless...
I have my map set (Positron - retina) and three other layers, two of them plotting different entities and the third one is a summary SVG icon displayed on each of the five continents.
This last layer is the one for which I would like labels to become visible based on which of the other two layers I selected from the Layers Panel on the right.
