A couple of months ago I decided to go to MintMobile, its a cell service to try out and I'm still with them and two or three months ago I logged in MyT-Mobile with no problem and found my account was still active and it had zero minutes tho I had the legacy plan. Now I went back to MyT-Mobile to sign in I typed my email and password correctly and I'm met with this. When I type in my phone number I press the done button and I see the green check mark and the loading screen and it just goes back like in the picture below. What does this mean?
