Hi bradzski,
Thank you for your post, sorry to hear you've been having issues with the Connect App since moving home.
When you move your services to a new address, a new account will be created for you and so you'll either need to create a new My Virgin Media account or have both your old and new accounts merged so you can continue using your existing log in details to sign into your new account. You'll use the same credentials to access the Connect App, so it's possible that you're still using your old details.
Can you please confirm if you've created a new My Virgin Media account or had the accounts? If not, that's most likely the cause of the issue and something we can sort for you from here.
Let us know
Beth
