This is on an iPad 10th generation iOS 18.5. It happens in live tv and with recordings. I’ve removed the app and reinstalled no change. I just tried it on my iPhone 12 same iOS with the same result. Same results with ATSC 1.0 and 3.0 channels.

Trying to turn off closed captions on iPad. Clicking CC crashes the app. On restart CC is still on. App version 20250515
