Let's say you still can't use subtitles on Peacock TV after following the steps above. You may need to make sure the audio/hearing captions option is enabled in your device's accessibility settings (iOS, Android, & Xbox). You can use this link to contact the Peacock customer service team if your device's settings allow subtitles but they aren't working. Customer service is available from 9 a.m. to 1 a.m. Eastern Standard Time.
