Why can the same YouTube TV episode have different ads?
Check whether you opened live TV, a saved recording or a video-on-demand version.

Look at the playback label first. A recording in the YouTube TV library, a live programme and a network-provided on-demand episode can show different advertising behaviour. The programme name may stay identical across the versions.
Open the version you intended
Find the episode in your Library and check the offered versions. If you joined a live broadcast late and paused it, you may be behind the live point. If you selected an on-demand entry, use YouTube TV’s help to check what advertising and controls apply to that version.
Preserve the example if something appears wrong
Record the programme, episode, channel and selected version before reporting a playback issue. A separate recording from another airing can behave differently, so use one identifiable version when comparing devices. Report a recording problem from the player when the appropriate option is available.
