Yes. In the STYLY app, select "My Page" to see a list of your published scenes. Then select the gear icon in the top right corner to access the app settings. Then select "Clear Downloaded Data" to delete any data that has been cached. When you access your scene again, you should be prompted to re-download the scene data.

The STYLY app seems to download my AR scene when I first load them, but if I make changes, is there a way to manually delete the cached scene so that I can be certain my changes are loaded when I view the same AR scene again?
