A real pain point for me lately has been that any time I update an Arcade expression I am using for symbology in a web map, it resets the symbology I have already set, especially annoying when the output from the Arcade expression is the same options as I had already set.
Why is this? This should not be the case, this is really annoying when I have a dozen categories set, that I then need to reconfigure any time I make any changes to the Arcade expression. Please add a fix so this does not happen, or at least give the user an option to have it start from scratch.
