Thanks for coming back to us ab101 and apologies for the delayed reply.
I've tried to do some tests today and the box appears to be offline. Can you switch it on for me and let me know so we can run some tests.
I've also noticed you've got a hub 2ac, if you're happy to do a self-install would you like a free upgrade to the hub 3?
The V6 box, is this connected to the internet wired or wireless please? If it's wireless can you try a wired connection and vice versa to see if this'll fix the issue.
Is Netflix the only app affected or are there other ones that this happens on?
Kind regards,
