VPN Tunnel not enabling JIT

[PatFussy69]

I have signed and installed Jitterbug 1.3.1 using UDID Registrations iOS App Signer, and enabled the local device VPN Tunnel, but it doesnt enable JIT. Ive tried on both UTM and Dolphin. When i go into the app and select my device (13 Pro Max iOS 1.16.02) it pulls up the pairing screen with "no files found". Im not sure what else i need to do, or if did something wrong.
