We're in the process of migrating to Touch UI and hope to be fully converted by end of June. In the meantime, our authoring team is still using the Classic UI. I just discovered an issue with the html5smartimage widget type where the renditionSuffix property doesn't get picked up by the widget once it's set. I'm able to set the fallbackRenditionSuffix and it works, but not the renditionSuffix property.
