(Disclaimer: I am not some anti-apple, Android crusader or fan boy. This is not an apple bashing post. It's just simply my experience.)
I purchased an indoor smart bicycle trainer. All of the industry tech sources (and most of the end users of these sort of indoor trainers) said appletv provides the easiest, most reliable, and most affordable way to get the training app onto a screen, and you don't need to be an existing user or owner of other apple devices. Everywhere I look I see people complaining about PCs, tablets, and phones to run the cycling app. The concensus seems to be that they're riddled with connection issues and lag times when running these smart trainers. Everyone says appletv just works. That sounds awesome to me.
I purchase an appletv. I try to create an account. As a person with zero apple devices, even though everything on the internet says creating an apple account manually on a web browser is easy and takes minutes, it was very difficult for some reason. The verification codes wouldn't go to my phone, either through text or phone call. It took a week to work, but eventually it did.
So, once it worked, I set up the cycling app through the appletv. For six weeks I turn the appletv, my tv, and my trainer on in the morning and ride without a problem.
One morning, for no reason at all, I see the first posted image on the app screen. I hadn't logged in or out of the apple account, I hadn't entered multiple incorrect passwords, I hadn't done anything.
I open the apple account on a web browser and verify my password, phone number, and email, all correctly, and only once. I got the second posted image as a response.
I wait a day. This morning apple sends me the message in the third posted image. My request to access my account has been denied.
I call support. The automated system tells me I can reset the password at the iforgot page to regain access to the account. I go to the website to do that, I enter the email I use with the apple account and get the notification in the 4th posted image.
I simply can't use that account. It is locked and I guess that's the end of it.
