Fire stick won’t connect to tv subscription

Have a new fire stick and trying to log in to apps like ESPN with tv subscription from midco. When I put in my info, it acts like it is working and then sends me back to subscription page. This is only for apps that I have to put my subscription info in on fire stick. Some tv apps I verify with a code from my phone and it works perfect. Anyone have any help? Thanks!
