I had to buy a new router to replace an Ax5400 which had a hardware problem. I can't for the life of me get my homeshield subscription to work on the new router. I've tried factory resetting everything, unbinding, rebinding, uninstalling & reinstalling everything. Every time I open up tether it reminds me that homeshield isn't applied but when I try and do it (I would have tried hundreds of times) it comes up with the following message:

Couldn't apply HomeShield Subscription Service to your network.

Please try again. If the problem still persists, please contact our technical support.

I've contacted tech support and waiting for a reply but this ongoing issue is very annoying.
