Firstly, I'd like to say that I am new to Geodatabases and Annotation layers.
I have an Annotation layer with Major and Minor road features that are styled according to their Annotation Class, "Major Style" and "Minor Style", which I note as AnnotationClassID 1 and 2 respectively and I wish to change the style of all Major road features.
I tried closing the layer in ArcMap, double-clicking it in Catalog to get "Feature Class Properties" dialog box, select "Annotation Classes" -> "Major Style" and changing the colour from green to red as a simple example.
But when I reopen the Annotation layer, the Major roads are all still green.
Another way I tried is directly change the SymbolID which does change the style BUT the FontSize automatically changes from 36850 to 8 reducing the text to a dot!
What is the correct way to apply a global style change to all Major road features in my Annotation layer?
