# Mobile RUM on React Native and Flutter, plus better shared dashboards

> Mobile RUM expands to React Native and Flutter, shared dashboards can stay live indefinitely, and Metrics Explorer queries can be saved to dashboards or alerts.

### Improvements

- **Applications (RUM)**: Mobile RUM now supports [React Native](https://last9.io/docs/real-user-monitoring/react-native/) and [Flutter](https://last9.io/docs/real-user-monitoring/flutter/), on top of the existing native iOS and Android SDKs
- **Dashboards**: [Shared dashboard links](https://last9.io/docs/using-dashboards/#sharing-dashboards) can be set to never expire (Forever), instead of timing out after 3 days
- **Metrics**: Queries built in [Metrics Explorer](https://last9.io/docs/metrics-explorer/) can be [added to a dashboard](https://last9.io/docs/metrics-explorer/#adding-a-query-to-a-dashboard) or [turned into an alert](https://last9.io/docs/metrics-explorer/#creating-alerts-from-queries) without rebuilding the query elsewhere

### Fixes

- **Dashboards**: Logs and traces panels on shared dashboards errored out with "Unsupported telemetry type" — only metrics panels would render
- **Discover**: Selecting an individual host from the node-exporter heatmap returned no data because the host-view queries filtered on a label that wasn't present on node-exporter metrics
