Our latest mobile SDKs do not support visual labeling. We recommend using the live data feed and explore events page to label mobile events. We hope to bring visual labeling to the new SDKs in the future and we continue to invest in new ways to label events.
If visual labeling is important to your workflow, you may wish to remain on our classic SDKs, which do support visual labeling. See our Android Classic and iOS Classic installation guides for complete details about these SDKs, including steps to use mobile visual labeling.
