Doesn’t work with new phone – Vonage Home Extensions Review

I’ve had Vonage for 15 years and started using the Extensions app when it first came out. It worked well, no problems until I upgraded my phone. Now the app doesn’t work. I can’t log-in because it says my home phone (my Vonage number) is invalid. I called support and they were unable to resolve the problem - she told me to try logging on later! I’ve emailed support but no reply and it’s been a week. Disappointed because this app worked very well for me.
