Hi Kelly,
Thanks for the reply. I get this, but I'd like to emphasize that this is a poor user experience. There are lots of configurations I can do on a layer: filter the data, hide or show the legend, disable or enable editing, add or remove labels, enable or disable popups, etc... all of these can be reversed, except for style changes. This should be similar to the other configuration changes, meaning there should be an option to clear the style.
Further, I may put a lot of time and effort into configuring a layer. The popup alone could have numerous fields which need formatting, aliases, perhaps hyperlinks, arcade statements, charts, etc.... Why make users throw all that away and start over just to get rid of a style they don't like?
