After signing up for Shaw Mobile, I can no longer use my Shaw ID credentials to register the current device to Shaw Go Wifi using the new registration form. Upon entering my perfectly valid credentials, the form immediately rejects them as invalid. For some reason Shaw decided to remove manual MAC address registration, which is how we used to do it. Is anyone else having this problem?

I have tried the gamut: resetting passwords, disabling 2FA, multiple browsers, multiple devices, safe mode, using Shaw's temporary code via support, etc. Nothing works. This is extremely frustrating as it is one of the reasons I use Shaw. Support has been a complete waste of time, forcing me to unnecessarily repeat the same steps to no resolution. The problem feels like it's on Shaw's end. 

Anything out there that people have found for a workaround?
