@TeamYouTube hi, don't know what's happening but some of my subscriptions have disappeared when on the app on PS4 but they are there on my phone app. I did some correlation and noticed that it's all music channels that aren't showing up... Any ideas?
To clarify, YouTube doesn't automatically unsubscribe users. You may want to take a look at our Help Center article for more info: https://yt.be/help/vL6K . Also, have you already tried resetting the app on your PS4? Here's how: Settings > Reset app. Hope this helps.
