Im having similar problems as other new customers when I try and access the "My account" tab I get an error message telling me something went wrong and it prompts me to reload the page, which results in the same error.
I can click on the "View my bill" option but that just gives me this message
"Thanks for your purchase, Mark!
We're getting your account set up. Check back soon to track and activate your services."
I have tried logging into other devices with WiFi turned off using Data
I've also tried clearing cache and cookies on multiple browsers.
