FaceTime calls not working on WiFi

[Sham80]

Help! I have rebooted and reconnected everything three times and no luck. FaceTime calls keeping dropping sound and connection is slow. Can’t check virgin connect app as it won’t even recognise my hub

Login to the Virgin Media online account and disable Child Safe.

Failing this, set your device to use a Public DNS so as to bypass Child Safe.
