Why is there no option to sign in using mobile in roku apple tv app? I can't sign in using remote, maybe because 2FA?

Hello _momer_,

We would like to see how we can help you with your Apple TV app. Follow the steps in this link to successfully sign in to the app: Watch on Smart TVs and streaming devices

"Roku

1. On your Roku home screen, select Search Channels.
2. Search for “Apple TV.”
3. Follow the onscreen instructions for adding a channel, then choose the Apple TV app .
4. When added, the Apple TV app appears in the channels section of the home screen.
5. Select the Apple TV app to open it, then sign in with an Apple ID if prompted.
6. Note: If you don’t already have an Apple ID, you can create one on the Apple ID website. You need only one Apple ID to use Apple TV app services. For more information, see the Apple ID FAQ."
