A check for Pluto TV
When a channel entry is live and the show has moved on, open the on-demand search for that exact title. Keep the schedule listing and replay result in two rows. If only the channel timeline is wrong, compare the local edition of Pluto TV before trying a reinstall.
Check on the intended screen
Open the app catalogue on your actual device and confirm the publisher and region. Sign in only through the service or documented billing issuer.
Keep a title-level test
Use one title, episode or fixture that you can identify. Record whether the app launches, the account signs in and the item plays.
