The only TVE source I have on Apple TV is YouTube TV and Philo.
Today I Found TNT, TBS and TCM works, couldn’t find CNN tough.
That’s weird as Turner were hostile against giving TVE access to non-
traditional providers.
WarnerMedia TVE channels became available from some OTT providers about 3 or 4 months ago. According to the availability chart, you should get CNN.

That's intresting I don't recall any of such announcements. Does it have something to do with ATT merger with Discovery thing?
