Check the delivered app collection
Xumo says its available TV and Stream Box applications arrive preloaded rather than being downloaded individually. First inspect the current collection and confirm the exact app name. A personal home-row arrangement is not necessarily the complete collection of supported applications. An unsuccessful title search is not the same observation as an absent application icon.
An app being available on another platform or in another market does not establish its availability on this television. Keep the model and region with the app request before using a broad installation tutorial that assumes an Android store.
Use the operation intended to update apps
For the Teal television interface, Xumo documents System management, Resets and updates, Refresh apps. Its help says refresh updates existing apps and adds new ones that have been made available. The process can take a short time while other television menus remain usable.
Observe the refresh message and then inspect the application collection again. A completed refresh is evidence that you performed the update step, not a promise that an unsupported app will appear. If the app is still absent, ask Xumo about support for the exact model and market.
Preserve local account state
The same help page describes a separate locally stored data operation and warns that app logins, game progress or recently watched information may be removed. Clearing that data is not the documented way to request a newly supported application.
Before any later data-clearing step recommended for an actual app fault, make sure you can recover the relevant sign-ins. For the missing-app question, provide the model, interface and refresh result first. This keeps an application-availability issue from becoming an unnecessary account-recovery task after a destructive cleanup.
