Some users use the same MAC address on multiple devices to keep their interface identical, though providers usually restrict this to one active connection at a time.

If your MAC-based service is no longer working in TiviMate due to a "patch," consider these steps: Switch to Xtream Codes : If your provider allows it, use Xtream Codes (Username/Password)

The error sounds technical and scary, but it is usually just a communication breakdown between your app and your IPTV provider. In 90% of cases, a simple message to your provider with a new MAC address solves the problem instantly.
