Apple TV app on iPad opens to Family Sharing, missing Home or Apple TV tab

I have an active 2 TB iCloud+ subscription in Nigeria, which now includes Apple TV. Apple TV works on my iPhone with the same Apple Account. On my 6th-generation iPad running iPadOS 17.7.11, the Apple TV app opens directly to Library → Family Sharing → another family member, and there is no Home or Apple TV tab. I have reinstalled the app and restarted the iPad, but the issue remains. How do I resolve this?
