Quick Answer
Remote control apps work best on trusted local networks with supported TVs, awake devices, allowed helper apps, and platform features exposed by the TV or computer. Some failures are not fixed by reinstalling the app because the limitation is in the TV firmware, network, router, firewall, or operating system policy.

Known Limitations FAQ
Should I reinstall the app if a limitation applies?
Usually no. Reinstalling cannot change TV firmware, router isolation, hotel Wi-Fi policy, or Windows firewall rules.
Can support override TV or network limits?
No. Support can help identify the cause and suggest workarounds, but it cannot change a TV brand’s API, a hotel’s network policy, or a firewall rule on a computer you do not control.
Where can I check feature compatibility?
Open the supported TV devices and compatibility table for platform-level notes.
