Check the release stage
The BiTTU Android repair APK is a separate test candidate. Production Windows, macOS and iOS releases remain in preparation. Official WireGuard clients are a setup path with your own valid configuration.
Confirm what you are importing
Use a profile supplied by an operator you trust for a gateway you are authorized to access. Approve the platform VPN request when you intentionally connect.
Verify behavior after launch
Installation and startup are separate from a working tunnel. Check the handshake, expected routes, external address and DNS, then test interruption and recovery.
