I normally work with ArcMap 10.5 on a desktop, but with working from home have been using ArcGIS Pro 2.4. Because there are a lot of complicated symbologies in the layers I use that I do not want to make again from scratch, I exported .lyr files of the layers from ArcMap and saved them to the laptop so I could import the symbology from them. However, when I do this on ArcGIS Pro, the labels of the layer disappears.
First I add the polygon feature class to the map. Then I select the attribute field I want to label using Arcade in 'Label Properties' and click 'Label'. The labels appear fine. However, if I then import a symbology from a .lyr file, the labels disappear. Even if I then return the layer to single symbol symbology, the labels do not return. Applying the symbology before adding the labels does not make the labels display either.
Does anyone know what could be causing this?
