I also had this same problem about 6 months ago. At that time I had accidentally enable the multi-factor authentication in my online Armstrong Account. That brings the captcha into play. Once calling Armstrong and having them remove MFA from my Account I was able to add the Armstrong TVe service back in as a provider.
Same result after loading the pre-Release update 4/26/26 - now getting the authentication error failure again where it appears to be waiting for a check in the captcha checkbox. MFA not on in online account.
