Known Limitations

Known Limitations

Tilecast reports platform limits instead of presenting them as completed capabilities.

One fullscreen zone

Playback currently uses one fullscreen zone.

Not currently supported:

• multi-zone layouts
• compositions
• simultaneous independent videos
• arbitrary HTML layout builders

The Layouts route in Studio is planned, not a completed feature.

No proof of play

Tilecast has device status, synchronization state, command results, and operational audit records. It does not currently claim proof-of-play reporting.

The Activity reports route is planned.

No authenticated Website Sources

Website Sources do not store usernames, passwords, administrator-supplied session cookies, or other website credentials.

They are intended for public or otherwise directly reachable pages.

Website host restriction is not a full proxy

The allowed-host setting restricts top-level navigation. Tilecast does not intercept every subresource request and does not claim complete third-party domain blocking.

No silent APK installation

Player updates use Android's package installer.

Depending on device and provisioning, a person may need to:

• allow unknown-app installation
• approve the installer
• return to Tilecast

Tilecast does not use root, ADB deployment, simulated taps, or hidden APIs to bypass these prompts.

Standard Reliability is not a hard kiosk

Standard Reliability can return to Tilecast with approved Accessibility Control, but Android may still allow a user to leave the app.

Only capability-confirmed device-owner lock task is labeled Managed Kiosk.

No direct HDMI-CEC commands

Power Assist uses Android sleep and wake behavior. A device may relay that to a TV, but Tilecast does not send raw CEC commands.

Player wake does not prove TV power, input selection, or visible playback.

No recovery from every physical failure

Tilecast cannot recover by itself from:

• unplugged or failed hardware
• power that is not restored
• changed Wi-Fi credentials
• captive-portal approval
• Android permission prompts
• a TV on the wrong input
• firmware that blocks boot launch

Offline changes cannot arrive

Cached playback and previously received schedules continue offline.

An offline player cannot receive:

• newly uploaded content
• a new manifest
• a new emergency
• a new command
• a new update deployment

One organization per installation

Tilecast is not multi-tenant. One installation manages one organization.

Run separate installations when organizations need separate owners, data, and security boundaries.

Fixed command set

Player commands are typed and fixed. There is no arbitrary shell, SQL, executable, URL, or script command.

Player updates are Tilecast Player only

The Player update system does not update:

• Tilecast Server
• Docker
• PostgreSQL
• the host operating system
• TV firmware
