Hi Lisaashfinn, thanks for your post.
Sorry for the trouble you've had with Netflix & Amazon Prime via your TiVo apps.
Have you been able to check for related known issues on our service status page: virg.in/service? If you sign in from there you can also run tests on your equipment which may offer a solution.
Also - if you have more than one box, have you noticed if the issue impacts all of them or just one in particular?
If there's nothing obvious that could be causing the problem don't hesitate to let us know so we can take a further look.
Alternatively you can text our cable-care team on 07533051809 (Mon - Sat 8am - 8pm) or give us a call on 150/ 0345 454 1111.
Tom
