3rd party apps on Roku

I recently got direct tv. On my Roku I’m trying to log in to apps like ESPN, food network, TNT. It acts like it authorises me when I login then when I pressed play it says I’m not authorised. Same thing in every app. Those channels are part of my subscription! I have spent hours on the phone and no one has a clue what to do. Anyone else have this problem and how did you fix it? Thanks
